Q & A:

We are currently using your 305 thermometer, and I see '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?


This could be happened

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 get damaged and should be returned back to our distributor for after sales service.
