Using the function accuracy time interval which
the UUT test signal connected its output terminals can easily performed. Using the
function capacitance measurement function UUTs megaohmmeters can verified.r. this way the calibrator can simulate the above mentioned parameters.o.2 Rearpanel
The rear panel the calibrator includes ventilation holes, power cord socket with fuse, mains voltage selector,
mains switch, IEEE 488 connectors for connection GPIB bus and type plate with serial number.
H igh voltage capacitance
The calibrator contains three high voltage capacitors with nominal vales 10, 50, 100 nF.The function designed calibrate TIMER function UUTs, like HIPOT testers,insulation
metes, programmable megaohmmeters, etc.

Fig. four different resistance values can step step connected the output
terminals selected time intervals.
S Short current easuring
The function allows measuring short current supplied UUT when the output terminals are
shorted.
D Sim ulator polarization/absorption param eters
The function can simulate various polarization/absorption indexes often built-in the UUTs. The
functions enables switch over the output resistance predefined time from one value another
value.
