Q. &  A.:

We are currently using your 307 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.

Q & A :
MY  main doubt was the adjustment of both OFFSET ?

The offset on the face of meter is just for slight adjust.

If there is a great error, this is not workable and you’d better

to return it back for further service..
