14.4. Troubleshooting
１．
In the Case that Proper Results are not be Obtained.
Use the self-check function. Refer to 8.1.Self-Check Function .
Check repeatability. ( Weigh the same mass several times in
the weighing mode.) A taller mass may touch the
glass-housing. Use a short mass if possible. If a tall 50g mass
is used, open the heater cover and avoid external influence.
The height from sample pan to glass-housing is 26 mm.
Check whether the test sample can be measured correctly.
Avoid the breeze from an air conditioner and vibration.
Check sample condition. Refer to 5.3.Proper Operation for Precision Measurement
Check measurement procedure and pre-heating process. Refer to 5.3.Proper
Operation for Precision Measurement
２．
In Case that the Lamp does not Light or it takes Too Long to Reach the Drying Temperature.
It requires six seconds to light the halogen lamp using
the START key.
When the heater cover is opened, power is not
supplied to the halogen lamp.
When an overheat has occurred, power is not supplied to
the halogen lamp until the halogen lamp becomes cool.
Check the rated voltage of the halogen lamp that is
printed around the holder.
Read the power supply voltage label on the back of the heater cover and confirm that
the rated voltage of the halogen lamp is correct for your power supply voltage.

100 - 120 V AC 100 V to AC 120 V AC 120 V AX-MX-34-120V
200V - 240 V AC 200V to AC 240 V AC 240 V AX-MX-34-240V
Is a fuse blown? Check the fuses after removing
the power cord. Check the rated value and put
new fuses into the correct holders.
Do you measure a lower drying temperature after
a high drying temperature? If the lamp is hotter
than the drying temperature, the measurement
can not be started.
Check that the sample pan is cool.
Other cases, the halogen lamp may be defective.
Replace with a new halogen lamp. Refer to "14.2.
Replacement of the Halogen Lamp".
