Battery Cell Insulation Tester 11210 User’s Manual
8-2
8.2 Panel Description
8.2.1 Front Panel
(1) Voltage Input Terminal (+)
There are two equipotential BNC terminals where the lower one connects to the 11210
current test terminal and the upper one connects to the DUT. See Figure 8-1 for the cable
connecting diagram.
(2) Voltage Input Terminal (-)
There are two equipotential concave terminals where the lower one connects to the
11210 current test terminal and the upper one connects to the DUT. See Figure 8-1 for
cable connecting diagram. As the terminal input voltage is very high [V (DC) = 0V ~
-1000V], be aware of high voltage hazard
Do not touch the test terminal or the DUT when the light of testing status is
on or blinks.
(3) Voltage Trigger Rotary Knob
It sets the triggering voltage ranged from 20V to 980V. When the 11210 output voltage is
set higher than the set trigger voltage, the A112102 will start sending out partial
discharge simulation signals. In the meantime, the orange PD LED light on the front
panel will blink. If the 11210 output voltage is lower than the set trigger voltage, the
A112102 does not act but there is still high voltage input and the DANGER LED red light
on the panel will be always on.
When the A112102 PD LED blinks but the 11210 does not show any PD
measurements and PD fail messages, it means the A112102 has sent out
the partial discharge simulation signal, but the signal level is smaller than
the 11210 PD Compare setting (see section
6.4.2), thus no PD relate info
(4) PD Interval Rotary Knob
It sets the partial discharge time interval ranged in the range of 0.1sec ~1.1sec. The user
can use time interval and test time to count the total partial discharge numbers. This knob
is invalid when the PD mode sets to Single.
