What to do if my Grimm Measuring Instruments says 'PLEASE RECHARGE'?
If your Grimm Measuring Instruments displays 'PLEASE RECHARGE', it means the battery charge level is below 10%. To resolve this, charge the battery by connecting the power supply.
Why my Grimm Mini-LAS 11-R Measuring Instruments shows 'NO OPERATION'?
If your Grimm Measuring Instruments shows 'NO OPERATION', this indicates that the battery charge level is at 0%. To fix this, charge the battery by connecting the power supply.
What to do if my Grimm Mini-LAS 11-R Measuring Instruments displays 'PUMP CURRENT TOO HIGH'?
If the Grimm Measuring Instruments displays 'PUMP CURRENT TOO HIGH', it could be due to the motor current exceeding 100%, possibly from a blocked intake or discharge. Try placing the device in a drying cabinet for a few hours, as the pump may be blocked by condensate. As an alternative, contact service, but do not open the device.
How to fix 'FATAL ERROR PLEASE CHECK' on Grimm Mini-LAS 11-R?
If your Grimm Measuring Instruments displays 'FATAL ERROR PLEASE CHECK', it could be due to lint obstructing the laser beam within the device's intake to the measuring cell, or a laser failure/hardware defect. Try cleaning the measuring chamber.
