Q & A:

We are currently using your 305B thermometer, and I see the 'OL.'mark appears when I turn it on. This mark never disappears and I cannot use this device. What does this sign mean? and what should I do in order to eliminate this?

 

Answer:
This could happen
1. The sensor got damaged.
You’d better try to change another new sensor to check if it works well.

2. If you measure temperature over 200 deg C,
the meter will show “OL” to let you know you should change
the resolution from “ O.1 “ to “ 1 “.

3.  Before the battery is consumed up, the meter will shall "OL"" too.
4. Finally, the worst possibility is that the meter gets damaged and should be returned back to our distributor for after-sales service.



Q & A:
We are facing a thermometer with a 0L display.
the terminal connection is correct.
I am using this model to measure 245degree temperature.
Is it due to over the limit of reading?
But I am sure that this thermometer can read more than this. Am I right?

Answer: You are right.
Please refer to the manual and you should switch its display decimal from o.1 to 1.0 because It is only 3 1/2 digits. 
 


Q& A: 
I would like to ask what is the problem when our thermometer is showing
negative reading instead of positive reading when we are checking a high
temperature solution.
Is there any way to troubleshoot this?

Answer:
You probably use a flawed thermocouple probe
and insert the thermocouple 2 pin reversed.
The narrow pin is positive, broad one is negative.
Please check.
