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 6.3.Proper Operation for Precision Measurement

Check measurement procedure and pre-heating process. Refer to 6.3.Proper

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 "15.2.
