Table 4 : Setup parameters of DIELECT function
6.4.1. Measurement modes
The instrument allows the selection of the following operating modes:
¾
Manual
mode
Æ
The test voltage is maintained constantly until the
START/STOP
key is pressed (see Fig. 36). The measured discharge current is compared with
the set limit value and the result is stored in memory
¾
Burn
mode
Æ
The test voltage is maintained constantly until the
START/STOP
key is pressed (see Fig. 36) but the result is NOT compared with any limit and is
NOT stored in the memory (functional test)

¾
75% Ramp
mode (
single ramp
)
Æ
When the
START/STOP
key is pressed, the
test voltage rises up to 75% of the nominal voltage then it takes 5s to reach the
nominal value. It is subsequently maintained for a time defined by a
programmable timer (see Fig. 37)
