Auto Power-Off; Some Notes About Accuracy - TENTECH MO2Ke Manual De Uso

It indicates that the value is the one retained in the display when pressing
the hold button.
It shows that the battery is quite discharged. Recharge the battery.

5. Auto power-off

The Auto-Power-off function turns OFF the equipment consumption in two
situations:
During the measurement: after 15 minutes of operation, without
•
checking the battery status.
Idle equipment - after 15 minutes of inactivity.
•
The equipment has a protection system that automatic turn OFF the
MO-2Ke when the battery charge reaches the minimum level.

6. Some notes about accuracy

In order to obtain the specified accuracy, the operator has to adjust the
test current to a value higher than the 80% of the nominal value. If it were
necessary, it is possible to use a lower current, but by doing this the
accuracy will be affected. MO-2Ke has an auto-compensation system that
automatically eliminates the error produced by internal offset. Thus, it is
not necessary to carry out measurements by reversing the polarity in
order to compute the average value. Nevertheless, if the operator suspect
that there is a difference of temperature between the contact points that
would generate thermoelectric voltages, it is necessary to carry out two
measurements by reversing the current cables and so, the circulation
sense of the current through the resistance under measurement. The
resistance value to be measured will be the average between the values
in one sense and in the contrary (direct and inverse current).
