Technical Specification
DIELECTRIC STRENGTH TEST FUNCTION
Output voltage
-
100V (for 5000V full scale) or 1000V (for 50000V full scale) to Umax AC (50 or 60Hz - to be specified when ordered)
-
Accuracy : ± (2.5% + 2U) of the reading voltage (1U=1% of the full scale) through motorised variac (24 seconds are necessary to reach the full scale), with the detection modes :ΔI, IMAX or ΔI+IMAX. Voltage regulation is made by a motorised variac.
Voltage reading
-
On a digital kilovoltmeter connected on the output terminals
-
Accuracy : ± (1.5% + 1U) of the displayed voltage (1U=1% of the full scale)
-
Display : 3 digits (example : 25.0 kV)
-
Resolution : 3 digits (example : 500 points for Umax = 50.0 kV)
Regulation
Current
Current reading
-
On a shunt resistor inserted in the test circuit
-
Accuracy : ± (2.5% + 2U) of the displayed voltage (1U=1% of the full scale)
-
Display : 3 digits (example : 99.9 mA)
-
Resolution : 3 digits (example : 999 points for Imax = 9.99 mA)
Breakdown detection
-
“DELTATEST” detector adjusted for ΔI = 10% of the full scale ± 10% with 10 μsec. ± 20%.
-
Total insensitivity to current due to the resistance and the capacitance of the device under test
-
“IMAX” detection by maximum current adjustable from (0.004xfull scale) to (Pmax/Umax) in AC voltage by current steps of 1 digit (example : for 999 mA, steps are 1 mA, for 20.0 mA, steps are 0.1 mA)
-
DELTATEST and IMAX mode combination
Breakdown indication
signal
IMIN threshold function
DC voltage (option)
Timer
-
Rise time and fall time adjustment from 27 sec. up to 999 sec. in AC voltage
-
Hold time adjustment from 1 sec. up to 999 sec. in AC voltage (up to 60 hours with DTMGPro PC software)
-
Quickmeas (option) in PLC and RS232 from 200 ms test time for high speed production testing
