the maximum programmed voltage. Each voltage step is applied during one
minute, and the resistance is measured before going up to the following
voltage. The test result is calculated with this formula:
After the test is finished, the value can be recovered by pressing the
PI
key.
Battery status check
During the measurement, it is possible to check the battery status. In order
to do that, this key must be pressed and the indication displayed must be
checked. If the charge is enough, it will read "BAT OK" or "LOW BAT",
should it be recharged. The analogue bar-graph will give an approximate
idea of the remaining charge percentage (at least 20% is required for a
normal operation). When the battery charge reaches the normal operation
minimum value, the message LO BAT appears automatically in the area
where the test tension value is indicates, alternating it every 1 second.
Built-in printer
In order to enable the printing function press key 1. Measured values will
be printed each 15 seconds, and the Dielectric Absorption Index and Po-
larization Index will be printed after 1 minute and 10 minutes respectively.
Printing may be started or stopped at any time during the test. However, it
is convenient to turn the printer on before starting the test in order to print it
complete, including the heading.
Auto power-off
The Auto-Power-off function turns off the equipment consumption (inde-
pendently of the timer function) in two situations:
•
During the measurement – After 35 minutes of operation, without al-
lowing that the battery status checking function is carried out during that
period.
•
Idle equipment – After 10 minutes of inactivity.
