11. Troubleshooting: Before Contacting Support
If you find any abnormalities or become unable to operate the instrument, first
check for the following items. If you still cannot solve the issue, please contact
your retailer or our company.
(1) The instrument does not operate when power is turned on:
- Is the orientation of the batteries in the correct manner?
Reset the batteries.
- Have the batteries been depleted?
Install new batteries.
(2) The indicated values of temperature are unstable:
- Is the element of the probe almost broken or is the probe deformed?
Do an appearance check of the probe.
- Is the probe connector inserted fully?
Re-insert the connector.
- Is the probe sufficiently making contact with the object of measurements?
Change how to set the probe.
- Is the measurement environment in a high electromagnetic field (such as a
large motor)?
- Relocate the instrument or use the shield.
(3) If measurement errors are too large:
- Are the thermocouple types of the probe and the instrument the same?
Replace the probe.
- Is the head of the probe deformed?
Replace it with a new one.
(4) Keys are not responding:
- Is there any burn out (broken element) indication shown?
Set the probe.
- Are any functions running?
Terminate various functions and retry to operate the keys.
