|The Digital Insulation Resistance Tester series have high performance, and safe configuration and improved electro circuit. It is one new item which has more fully function, higher precision and easier operation. It’s also one quakeproof, dustproof and damp-proof tester and can fit work environment of outdoor.|
The output testing voltage can be changed between 100V/250V/500V/1000V/2500V/5000V for different item no. The resistance can reach 200GΩ; the tester also can measure alternating voltage.
This Tester apply for all kinds or electric equipment and insulation materials such as transformer, electromotor, cable, switch appliance, etc.It is a perfect electrical testing meter.
Low power consumed CMOS double integral A/D transforming IC, auto-checking to zero, auto displaying polarity, displaying when low battery.
3 1/2 digits display with a max. reading of 1999
Has function of holding data and displaying signal.
LCD back light

Testing Rating Voltage
90～110% Testing Rating Voltage
1MΩ～200MΩ: ± ( 3.0%+5 ), 200MΩ～10GΩ: ± ( 5.0%+5 ), 10GΩ～200GΩ: ± ( 10.0%+5 )
20MΩ: 10kΩ, 200MΩ: 100kΩ, 2000MΩ: 1MΩ, 20GΩ: 10MΩ, 200GΩ: 100MΩ
Scale of AC voltage
± ( 2.0%+5 )
Note: When the measured resistance is less than 5MΩ in any rating test voltage, the measuring time should not be more than 10 seconds.
Remark: fall down resistance
Rating test voltage
fall down resistance
Explaining: Minimum measured resistance means lower limit value of resistance which it ensure the voltage of two extremity of measuring is less than 90% of rating test voltage.
