Product ID: DIM-572

Digital Insulation and Insulation Continuity-
Voltage Tester


  • Originally designed unique products have   features ranging from insulation resistance testing.
  • Voltage (AC - DC) measurement with automatic  hold facility, continuity test with a short circuit
current of minimum 200 mA.
  • For Insulation Testing, the user can select the test voltage of 250V, 500V AND 1000VDC. It is
    utilized to accept a selection and to disable the Energy Save feature.
  • The Ohm Key is a multi-purpose key, you press it to select the Continuity Test, then you use it to
    Auto-null the test leads and fuse.
  • There is an automatic voltmeter which is accessed after start up.
  • The Voltmeter is the default mode of this instrument.

Digital Multifunction and Insulation Continuity-Voltage Testes

A new generation of modern digital multifunction testers is born. This tester has a range of new features
not even found in expensive advanced test equipments. Not only rugged, but designed to excel in harsh
environment, still, remaining low cost and affordable. It can be operated with rechargeable batteries,
alkaline or low cost general purpose batteries. This unique product has features ranging from Insulation
Resistance Testing, Voltage(ac-dc) measurements with Automatic Hold facility, Continuity Test with a
short circuit current of minimum 210mA. Two very unique features are found on this multifunction model

MOV and Gas Arrester Testing

Today, most equipments and electrical installations are protected by MOVS and

Gas Arresters, or a combination of these.

This tester can test the devices to establish if it is still operating correctly or not.

Energy conservation is featured on all these new advanced product. “ Auto-power-off” limits the test
duration to about 10 seconds to save energy. “Auto-power-off” can be turned off by simply keeping the
ON/TEST key depressed for more than 3 seconds while starting a test. This new tester has no moving
parts. All calibration are saved internally in a non volatile memory. Calibration can be done at any
calibration facility in the world without the need for dedicated calibration equipment. This makes tester
easier to maintain and lower the cost of calibration and maintenance. The calibration interval can be
extended without much problem. They comply to all the latest regulations, including UK.This tester
feature heavy duty protections in its circuitry. Safety features are built-in. For example, should you
connect the leads onto a Voltage, AC or DC, the tester will detect it. Switch itself ON and show the
voltage present on its leads. The tester will also buzz to inform the user of a safety hazard. We bring a
similar solution in the case where the user tries to start a test and measure on a live circuit. If this
happen, the tester will disable testing until the circuit has been isolated. This tester can function with
rechargeable or Ni-Cad or normal batteries.The circuitry can acept a wide range of power and still
perform properly.
