Error/Warning

describe

Solution

Close the lid and press' Read '

Lid open or lid detection failed.

Ensure that the lid is closed during the reading and re reading period

Low battery!

It's due to low battery power

• Install a new battery

If using rechargeable batteries, connect the USB/power module

ADC malfunction!

Hardware error causing reading failure

Readjust again

The detector signal is too low!

Insufficient lighting on the 180 ° detector

Check if the optical path is blocked

Please check the light

Out of range!

High turbidity - may be due to using only RapidCal ™ Calibration caused.

Calibration upper limit.

Dilute the sample

Below the range!

The measured absorbance is below the calibration range

• Repeat calibration

Please check the lights!

The signals from the 90 ° and 180 ° detectors are too low

2100Q: There is a problem with the light. Replace the light (please refer to the instruction manual for bulb replacement).

2100Qis: Please communicate with the department.

The temperature is too high! Turn off the instrument

The temperature has exceeded the instrument limit (>60 ° C or>140 ° F)

Turn off the instrument panel and let it cool down

RST： The average value!

The solid substance precipitates too slowly, and the reading mode is not suitable for this sample

Please select the 'Normal' or 'Signal Average' reading mode
