Dr Trust BP Monitor Error Codes: What They Mean and What to Do

Is your Dr Trust blood pressure monitor showing an error code, failing to inflate the cuff, displaying an irregular-heartbeat symbol or giving inconsistent results?

Many measurement problems can be related to cuff positioning, movement, batteries, power supply or incorrect measurement technique. However, some problems require inspection or service by the manufacturer.

This guide covers common troubleshooting steps for four Dr Trust upper-arm BP monitors available at Microsidd India:

• Dr Trust AccuTrack AFib 130
• Dr Trust iCheck Pro 116
• Dr Trust BP Check 122 W
• Dr Trust Pediatric BP 111

Quick answer: If your BP monitor reports a measurement error, stop the current measurement, check the battery and cuff connection, rest quietly, apply the correct cuff size and repeat the measurement according to the user manual.

Important: Error-code meanings differ between some Dr Trust models. Always check the exact model number and supplied manual before interpreting a code.

Dr Trust BP Monitor Error Code Chart

The following error meanings are documented in the manufacturer's BP Check 122 instruction manual.

They are provided as a reference for the BP Check 122 family. The exact BP Check 122 W revision and other Dr Trust models must be checked against their own manuals.

Do not use this chart as a universal Dr Trust error-code list. For example, an ERR 1 or ERR 3 message on another monitor may have a different meaning.

Consult the exact user manual, especially if the display shows a code not listed above.

ERR 1 – No Pulse Detected

In the documented BP Check 122 manual, ERR 1 indicates that the monitor did not detect a suitable pulse signal.

Possible Causes

• Incorrect cuff position
• Movement during measurement
• Arm not properly supported
• Measurement interrupted by external interference
• Difficulty obtaining a reliable pulse signal

What Should You Do?

1. Stop the current measurement.
2. Check that the cuff fits correctly.
3. Support the arm at heart level.
4. Rest quietly before repeating.
5. Remain still without talking.
6. Follow the model's instructions for another attempt.

If the monitor repeatedly cannot detect a pulse, or the user has symptoms such as dizziness, fainting or breathlessness, seek appropriate medical advice.

ERR 2 – Movement or Pressure Interference

For the BP Check 122 manual, ERR 2 indicates unnatural pressure impulses affecting the measurement.

Arm movement is one possible cause.

How to Reduce Measurement Interference

• Sit with your back supported.
• Keep your feet flat.
• Do not cross your legs.
• Support your measuring arm.
• Do not speak during measurement.
• Do not move the cuff or tubing.

Repeat only after the measurement conditions have been corrected.

ERR 3 – Cuff Inflation Takes Too Long

The documented BP Check 122 manual associates ERR 3 with excessive cuff inflation time or incorrect cuff seating.

Possible Causes

• Cuff not fastened correctly
• Loose air tube connection
• Twisted or obstructed tubing
• Damaged cuff or air tubing
• Incorrect cuff size

Safe Troubleshooting Steps

1. Stop the measurement.
2. Remove the cuff.
3. Inspect the cuff and tubing for visible damage.
4. Reconnect the air tube according to the manual.
5. Check the upper-arm circumference.
6. Refit the cuff correctly.
7. Repeat only if the equipment appears intact.

If the cuff repeatedly fails to inflate or holds pressure abnormally, stop using the monitor and contact manufacturer support.

Do not attempt to seal leaks with adhesive tape or modify the cuff's inflation components.

ERR 5 – Unusual Difference Between BP Values

The BP Check 122 manual describes ERR 5 as an unacceptable difference between systolic and diastolic pressure values.

This is a measurement error reported by the device, not a diagnosis.

Check cuff size, arm position, movement and rest conditions, then follow the manual for a repeat measurement.

If values remain unusual or the user has concerning symptoms, seek clinical advice rather than repeatedly attempting measurements.

ERR 8 – Excessive Cuff Pressure

In the documented BP Check 122 manual, ERR 8 is associated with cuff pressure exceeding 290 mmHg.

Safety warning: If the cuff inflates excessively, causes unusual pain or does not release pressure normally, stop the measurement immediately.

Use the monitor's stop function and remove the cuff once safe to do so.

Do not continue repeated measurements when excessive inflation persists. Contact manufacturer service.

Dr Trust BP Monitor Not Turning On

A blank display can occur because of battery, power-connection or device problems.

Check These First

1. Confirm that the correct batteries are installed.
2. Check the positive and negative battery polarity.
3. Replace depleted batteries with the specified type.
4. Inspect the battery compartment for damage or corrosion.
5. If supported, use only a suitable external power supply specified for the model.
6. Check whether the display starts normally.

Different Dr Trust models use different batteries.

Do not interchange battery sizes or power adapters. Use the power specification printed on the actual device or stated in its manual.

Dr Trust BP Monitor Cuff Not Inflating

If your Dr Trust BP machine starts but the cuff does not inflate correctly, check the following:

• Whether the cuff tube is securely connected
• Whether the cuff is correctly wrapped
• Whether the air tube is twisted
• Whether the batteries have sufficient power
• Whether the correct cuff is being used
• Whether the cuff or tubing has visible damage

A damaged cuff, leaking tube or defective pump may require manufacturer inspection or replacement.

Do not open the monitor, repair its internal pump or modify its air tubing.

Why Does My Dr Trust BP Monitor Show Different Readings?

Blood pressure naturally changes throughout the day. Two measurements taken under different conditions may produce different results.

Variation can also be caused by incorrect measurement technique.

Common Reasons

• Measuring immediately after exercise
• Recent caffeine or nicotine use
• Not resting before measurement
• Talking or moving
• Arm positioned below or above heart level
• Incorrect cuff size
• Different measurement times
• Device or cuff problems

For routine adult home monitoring, rest for at least five minutes and take two readings approximately one minute apart when advised.

Record the values and discuss repeated discrepancies with a healthcare professional.

What Does the Irregular Heartbeat Symbol Mean?

Several Dr Trust BP monitors display an irregular-heartbeat symbol when certain pulse irregularities are detected during measurement.

It may appear on:

• AccuTrack AFib 130
• iCheck Pro 116
• BP Check 122 W
• Pediatric BP 111

This symbol does not automatically mean atrial fibrillation.

An irregular pulse indication may have several possible causes, and the device cannot determine the cause from the symbol alone.

If the indication appears repeatedly, consult a qualified healthcare professional.

What Does AFib Mean on AccuTrack AFib 130?

The Dr Trust AccuTrack AFib 130 includes a manufacturer-advertised AFib screening function.

An AFib indicator suggests that the monitor detected a pulse pattern that may require further investigation.

It is not an ECG and cannot independently confirm or exclude atrial fibrillation.

Follow the specific AFib screening instructions for model 130.

If the indication recurs, seek medical advice. A healthcare professional may recommend an ECG or other rhythm testing.

Why Does My BP Monitor Display a Cuff Warning?

Some Dr Trust monitors provide cuff-fit indicators to help users identify incorrect cuff application.

If a cuff warning appears:

1. Stop the current measurement.
2. Check the upper-arm circumference.
3. Confirm the cuff range.
4. Apply the cuff directly on bare skin.
5. Align it using the manufacturer's markings.
6. Support the arm and repeat as instructed.

For the adult-sized models covered in this guide, the supplied cuff range is 22–42 cm.

Pediatric 111 comes with a 17–22 cm cuff.

A cuff from another model should not be used unless the manufacturer confirms compatibility.

Dr Trust iCheck Pro 116 MAC Mode Troubleshooting

The iCheck Pro 116 supports MAC mode, which averages two successive blood pressure measurements.

When using MAC mode:

• Remain seated during both measurements.
• Do not remove the cuff between readings unless instructed.
• Do not speak or move your arm.
• Follow the exact MAC button sequence in the manual.
• Check whether an error interrupted the sequence.

If a measurement fails, do not assume that a partial sequence represents a valid two-reading average.

Repeat only according to the device instructions.

Dr Trust Pediatric BP 111 Troubleshooting

The Pediatric BP 111 has a child-sized 17–22 cm upper-arm cuff.

Common challenges in pediatric BP measurement include movement, anxiety, unsupported posture and unsuitable cuff size.

A responsible adult or healthcare professional should supervise use.

If repeated errors occur, check cuff fit and follow the exact Pediatric 111 manual before interpreting any displayed code.

Do not use adult BP thresholds to diagnose hypertension in children.
