Grounding Resistance Tester | MT78XR

MT78XR Grounding Resistance Tester

Product Introduction

The mt78xr grounding resistance tester ıs used to measure the ınternal grounding resistance of electrical equipment, which ıt reflect the (contact) resistance between the total ground terminals of the electrical equipment. It ıs suitable for measuring the resistance value between the outer casing and the ground wire of various kinds of motors, electric appliances, ınstruments and meters, domestic appliance and so on. This series of tester according to the following standards:standard for household electrical appliances (IEC6035, GB4706.1-2001,  GB4706.1-1998), standard for lamp(IEC60598-1-1999,  GB7000.1-2000), standard for ınformation (GB8898-2001, GB12113. GB4943-2001,  IEC60065,IEC60950) and so on.

Application Area

Household electric appliances:tv, refrigerator, air conditioner, washing machine, dryer,  electric blanket, charger etc. Instruments and meters:oscilloscope, signal generator, dc power supply, switching power supply and other types of machine.

Lighting appliances: ballast, road lights, stage lights, portable lamps and other types of lamps.

Electric heating appliances:electric drill, pistol drill, cutting machine, grinding machine, electric welding machine etc.

Motor: rotating electrical machines,  etc.

Office equipment:computer, currency detector, printer, copier, etc.

Performance Characteristics

Test the maximum current 32a, ıt conform to the<GB4743.1-2011 standard>.

Test resistance, current, time are all display digital.

Test alarm value can be set arbitrarily, audible and visual alarm. When ıt ıs unqualified.

Four-terminal measurement method can eliminate the ınfluence of contact resistance on the measurement results.

Test time can be set arbitrarily. The minimum resolution of time ıs 0.1s over current protection, easy to operate, high reliability.
