In manual voltage regulation, due to the use of 3 and 4 keys,
only 1, 2 keys and start stop keys can be used to stop the
measurement operation.
When the test time or manual stopped, display shows as shown in the table of the
soft keys.

measured DAR :
1. Select more than 1 minute length measurement.
2. Select the appropriate voltage and start.
3. The instrument automatically record 15 s and 60 s resistance, and calculate the
absorption than after 60 seconds.
Absorption ratio calculation method: DAR = R60 / R15;

measured PI :
1. Select more than 10 minute length measurement.
2. Select the appropriate voltage and start.
3. The instrument automatically record 15S, 60S and 600S resistance, and calculate the
polarization index after 600 seconds.
