4. Press Up/down key to select configuration item to be set and press
corresponding soft key for setting. Set values through knob. Press [Enter] to
confirm the set values. Otherwise, the setting will not be effective.
After setting, press [Esc] to return to Measurement interface; when you
directly press [Esc] to return but fail to press the [Enter] key for confirmation,
the setting fails.
5. After Compare function is on, if Alarm mode is set to Display, the Meter
interface will display comparison results. If set to Beeper, the instrument will
give beep alarm. Meter interface of display mode is as follows:

3.8 Calculate Function

The IT5101 Series internal resistance tester provides Calculate function, and is
applied for instrument calibration or linear amplification of measured data.
Suppose that the current measured voltage is x, the value after liner
amplification is M*x+B, where M and B are set values.
In general, Calculate function is used to calculate other physical values related
to voltage and resistance. Suppose that there is a linear relationship between
resistance and temperature: T=M*R+B, where T means temperature, R means
resistance, and M and B are set coefficients, through measurement of
resistance value, you can display temperature result.
Set amplification factor and offset value following the steps below:
1. Press [Meter] key. Display current measurement status.
Abs: during judgment of comparer, read absolute value of voltage
measurement. Even in reversed polarity of battery, comparison still can be
realized based on absolute value.
V Mode: set voltage compare mode: Absolute (H/L) and Relative (Ref%).
R Mode: set resistance compare mode: Absolute (H/L) and Relative
(Ref%).
H: set upper limit of voltage or resistance.
L: set lower limit of voltage or resistance.
R: set basic value in comparison.
%: set percent of voltage/resistance value in comparison.
V-Comp: voltage compare result: Low (lower than compare range)/High
(higher than compare range)/In (within compare range)
R-Comp: resistance compare result: Low (lower than compare range)/High
(higher than compare range)/In (within compare range)
