§ Two-piece design for easy transportation Rugged and robust and only
14+22 kg (31+48 lb)
§ Handling up to 15 mA interference current into any lead of the
instrument or a signal to noise ratio of 1:20, secures stable readings and
correct data even in the highest interference switchyards.
§ Standard 50/60 Hz measurements as well as 1-500 Hz frequency sweep
reveals more details in the insulation characteristics.
§ Variable frequency source allows larger capacitance specimen to be tested
without the need for special resonating inductors
§ Advanced signal acquisition and noise suppression circuitry results in 25-
50% shorter measurement times
§ Individual temperature correction (ITC) feature enables an accurate
temperature correction of measurements taken at high and low
temperatures. Temperature table corrections are no longer required.
§ Two operation modes; Form-based, automated testing with PowerDB or
run your specific test manually controlled with Delta Control.
§ Enhanced safety features with safety hand switches, foot switch, warning
strobe light and a ground interlock system.
§ Optional resonating inductor provides capability of testing high
capacitance samples at high voltage.
