The typical voltage ramp
(dV/dt) is
1 kV/min which is the
default for S1 range. This
value is user adjustable
from the settings function
with the mode rotary
switch set to ramp. Up and
down buttons are used to adjust dV/dt to the required rate and OK
confirms the setting. Press and hold TEST to start.
The test will ramp the voltage until it reaches the selected test
voltage unless a breakdown or sudden fall in voltage is detected.
The result displayed after the test is the final insulation resistance,
voltage and current. If the result is saved a complete curve of
current (µA) and voltage (kV) is recorded and can be read into
PowerDB, PowerDB Lite or converted to a spreadsheet so that
the current vs. voltage curves can be compared to published
curves in IEEE 95-2002.
Remote control mode
Remote control of the S1 range is possible on all models via USB
cable only and the Bluetooth
®
link is disabled.
The remote control indicator must be attached to the right
side of the instrument
.
Coloured lights in the
dongle indicate remote
control status. When
the indicator is lit green
it means that remote
control is activated and
when red that the
instrument is not in
remote control mode.
Remote control mode is activated with the test mode switch pointed
at the remote control icon and the main rotary switch pointed at
V
L
.
All manual test modes can be setup, tests started and stopped
remotely.
