According to IEC 335-1; IEC 61558-1:2005 clauses 9.2,14,15 and other national standards in the relevant provisions. The tester is suitable for measuring the residual voltage of medical electrical and other equipment, with presetting fun
Mode 1: Test the remaining voltage instantaneous value after disconnecting the power supply for 1 second. Test time fixed, interval time 1s, input voltage shows valid value, test voltage shows peak value, exceed set alarm voltage value alarm. (Decay time judgment is invalid)
Mode 2: Disconnect the power of the test article to detect the remaining voltage instantly (display the actual value) and record the decay curve to calculate the decay time according to the decay percentage. (Voltage alarm judgment is invalid)
Recording time resolution: 0.01 sec
Voltage resolution: 0.1V
Sample voltage input 0~250V (user provided) (Accuracy 10-70V; Accuracy: ±3% of reading)
Residual voltage measurement range 0~100V AC/DC (Accuracy 10-70V; Accuracy: ±3% reading)
Measurement time 1-999s settable (in mode 2 only), ±0.1s
