■Model TOS1200 Withstanding Voltage Tester Current
Calibrator: For calibration of current sensitivity of
withstanding voltage testers
❏Calibration of Leakage Current Detection Sensitivity
As a result of containing an internal test load resistor, the
TOS1200 enables switching of ammeter sensitivity and load
resistance values automatically for easy calibration of the
sensitivity of leakage current detection.
❏Direct Reading of Error from Error Display Scale
The main scale consists of an error display scale ranging
from -10% to +10% around a central full scale value. Thus,
if the leakage current detection sensitivity of the withstanding
voltage tester is a value of 1, 2 and 5 steps or 1, 2, 4 and 8
steps, the error can be read directly from the scale. The
auxiliary scale consists of a ratio display scale in which the
full scale value is taken to be 1.1, thereby enabling
accommodation of values outside the range of the main scale.
❏Ammeter Ranges
The ranges of the ammeter consist of 0.5, 1, 2, 5, 10, 20, 50
and 100 mA, and values equal to 0.8 times those values can
be set. This is convenient for withstanding voltage testers
of the type in which leakage current detection sensitivity is
set digitally (1, 2, 4 and 8 steps).
❏Eliminates Need for Power Supply
The TOS1200 offers outstanding portability since it does
not require a power supply.
