Programmable Insulation Resistance/ Withstanding Voltage Tester

Specifications

Electric safety wall detecting function

Voltage rises as time, seeking for the breakdown points

Voltage falls as time, preventing reverse overshoot

Over-zero start prevents the damages for DUT

Test mode programmable

Voltage rise, voltage fall, test and dwell time programmable

Current Low-limit and up-limit programmable

Maximum power output can be up to 500VA

Can set offset value

LCD display with menu-guided operation

Arc detection (set up as current)

ACW to DCW to IR automatic switching function

20 memory groups, 8 test steps per group

Auto shift range in IR

Standard PLC interface, optional ports: RS232, RS485

Optional supply voltage 110V/220V,50Hz/60Hz. The tester will first check whether the input power supply right connected to N,L,G automatically after power on and give the prompt information if any of misconnection

Key lock, preventing operators from modifying testing parameters

Adopt 240*64 dot-matrix large graphics LCD displays setting parameters and testing parameters strikingly, visually

LCD contrast, buzzer volume, the retentive time of PASS signal can be adjusted by keystrokes

50 memory groups, 30 steps per group

Users can name freely memory groups as required, which maximum can be up to 14

Both Chinese and English operation interface

Standard PLC interface, optional ports: RS232CRS485GPIBUSBPRINTER

Control eight memory groups through PLC interface; level signal or contact signal can be selected as PLC test signal and if level signal selected, PLC high output level is 24V during the testing

Test results which maximum can be up to 9999 can be stored inside the tester or sent to the computer through RS232
