User displays, menu structure and navigation
GDT screen
The GDT screen is where the ring voltage of the GDT under test is displayed. The measurement is
performed by pressing the TEST button on the front of the instrument. The rate of voltage ramp in V/s used
in this measurement is congured in the Measurement screen.
If the LOG mode is switched on, the measured value can be read directly on the Log screen.
TVS screen
The TVS screen is where the clamp voltage of the TVS device under test (or SPD surge protector) is
displayed. The measurement is performed by pressing the TEST button on the front of the instrument. The
constant current setting used is congured in the Measurement screen. The only di󰀨erence between the
TVS and MOV modes is that the possible voltage at the test leads is limited to 200 V in the TVS mode,
while in the MOV mode a maximum of 1500 V DC is possible to drive the required constant current.
If the LOG mode is switched on, the measured value can be read directly on the Log screen.
