Permanent current measurement
Reading of the current thanks to shunt resistances in the test circuit.
The current is read according to two ranges (one shunt resistance for each range):
- G1 : from 0.0µA up to 100.0µA
- G2: from 100µA up to 1000µA
Display of the value on a 1000 points digital indicator.
The accuracy is the following :
- (1% + 0.2µA) in the G1 range
- (1% + 2µA) in the G2 range
Fault indication
By message on the LCD display, red and green LED, and audible signal (possibility to inhibit).
Memory storage of the breakdown voltage.
Memory storage of the leakage current in IMAX mode.
Cut off of the high voltage without over voltage.
Timer
(mode) MANUAL
The timer is not used during the test . The voltage output is manually controlled by pressing on the
UP/DOWN arrows. The test stops when a breakdown occurs or when pressing on the red push
button on the front panel.
(mode) DEFAULT
The timer is not used during the test. The voltage output is defined in the parameter VOLTAGE line.
The test stops when a breakdown occurs or when pressing on the red push button on the front
panel.
(mode) AUTO
The test is defined by three consecutive times during which the output voltage rises linearly up to the
preset value ( RISE time) , then is hold to the preset value ( HOLD time) and finally bring back to
zero ( FALL time).
The RISE time can be set in seconds, from 2 to 60 sec. by 1 sec. step, or can be set in V/s.
The FALL time can be set in seconds, from 0 to 60 sec. by 1 sec. step, or can be set in V/s.
In the case of ramps set in V/s, the value translated into seconds must stay between the time limits
given above. For example, if the test voltage is 5000VDC and the ramp up set by the user is
5000V/s, this value will not be accepted because it is equivalent to a ramp up time of 1s < 2s,
whereas if the value of the ramp up is 2400V/s, it will be accepted.
The HOLD time can be set from 1 to 999sec. by 1 sec. step.
