Regular Maintenance

Looking after your product can prolong its lifespan, provide more consistently accurate results and potentially reduce your parts and labour costs. We suggest the following measures to help:

  • Keep your product clean, using an in-use cover extends the life of keypads etc. 
  • Avoid prolonged exposure to harsh environments.
  • Power off your scale when not in use for prolonged periods, for laboratory balances, leave the product switched on but in standby mode.
  • Calibrate your balance at regular intervals.
  • Have your product regularly serviced and calibrated to ensure it continues to provide accurate results.

If you have a problem with your product see below:

  1. Read the common problems and solutions information below, to see whether you can solve the problem yourself.
  2. Check the user manual for error message explanations that are specific to your balance. For current products you can download user manuals here. For older, or legacy products please contact us regarding availability of a replacement manual.

If you are still experiencing a problem then either call one of our local service centres or use the contact form on this website, select service or spare parts and send us the details of your problem. We will review the details and get back to you.

We provide an inspection and quotation service for customers wanting to get their product repaired. A standard inspection fee of £25 per machine applies and is waived if the repair quotation is accepted.

Common Problems and Solutions

We have found that many service problems can be resolved if the user performs some simple checks on the scale or balance in question. Please refer to the table below to help identify some basic problems and solutions.

ProblemPossible Cause Common Solution
Battery will not charge

Mains voltage not present or too low.
Charging circuit failure.
Battery Failure.

Verify the batteries are rechargeable types.
Some scale use non-rechargeable batteries only.
Check power supply voltage is correct.

Cannot use Full Capacity

Over load Stops hitting pan support or hitting bottom of load cell.
Shipping screw not removed if applicable.
Electronic problem on A/D.
Parameters set incorrectly.
Load Cell or mechanics Damaged.

Look for obstruction under pan, shipping screws, and verify pan installation.
Check the weighing units used.

Display is blank/ Does not turn on.
Fuse in plug blown?

Mains power is turned off.
Power supply not plugged in.
Power supply faulty.
Internal battery not charged.
Display turned off.
Wrong power supply being used.

Check power is going to the scale and the switch is on.
Verify the voltage going to the scale matches the power supply labels on the power module or scale.

Display blank after turn on test or showing error message.
Display is locked.

Pan not installed.
Unstable weight.
Load cell damaged
Mechanics damaged.

Check the pans are installed correctly.
Try turning the scale on again.

Display is unstable

Drafts or air currents.
Obstruction under pan.
Sample is moving (animal weighing).
Vibrations through the table.
Temperature is changing dramatically.
Power supply faulty.
Battery low on charge.

Verify the scale is in a acceptable location and on a good table.
Verify the power supply is correct for the scale.
Re-charge/ change battery.

Not Linear

Overload stops hitting too soon.
Load cell or mechanics damaged.
A/D damaged.

Look for obstruction under pan, shipping screws, and verify pan installation.
If linearity can be set by the user it will be described in the user manual

Off Center Loading error

Adjust mechanics.
Overload Stops not correct.
Load Cell/ mechanism damaged.

Look for obstruction under pan, shipping screws, and verify pan installation.
OL appears on display

Weight on scale over permissible limit.
Pan support not seated properly.
Power supply faulty.
Load Cell or mechanics damaged.

Check the pans are installed correctly.
Try pressing Zero key.
Try turning the scale on again.

UL displayed

Weight on scale below permissible limit.
Pan has been removed.
Pan support not seated properly.
Power supply faulty.
Load Cell or mechanics damaged.

Check the pans are installed correctly.
Try pressing Zero key.
Try turning the scale on again.

Weight value incorrect

Calibration error.
Linearity error.
Unit calibrated with inaccurate weight.
Balance not level.
Obstruction underneath the scale.
Wrong unit of weight displayed.

Calibrate again, paying special attention to the mass used, the stability of the scale, and the weighing units required.
If linearity can be set by the user it will be described in the user manual.
Check pan is installed correctly and clear any obstructions.
Verify installation is acceptable.
