Tester
The calibrator includes an application SW, which facilitates automated testing of regulators and transducers. Tester
function combines the use of the calibrator as the source of precision signal with automatic change of output signal,
while the response of the unit being tested is measured by the calibrator’s built-in multimeter. The calibrator is
capable of subsequent processing of measured values, providing PASS/FAIL indication.
Tester function comprises of performance of a programmed sequence of up to 10 steps. For each step, the type and
value of output signal and the type and tolerance of input signal can be defined. If the input signal is not within the
tolerance limit, the respective step of the test program is considered failed. The time between individual steps can
be set as well.
