Digital Insulation Resistance Tester with built-in Multimeter, 3-3/4 Digits 3999 Counts, Backlit LCD, Data Hold, Test Voltage: 250V / 500V / 1000V, upto 40G.Ohms, Measures AC/DC Voltage, AC/DC Current up to 400mA, Resistance, Capacitance, Frequency, Diode & Continuity Test Facility.

DIT-321 Auto-range Digital Insulation Resistance Tester is a combination of Insulation Resistance Testers and Digital Multimeters. It has complete functions, features, high accuracy, reliability in operation, and convenience in use.
Output test voltage can be switched between 250V/500V/1000V.

An ordinary insulating resistance meter can not measure the output high voltage of its own. When the output high voltage of the insulating resistance meter doesn’t conform to the rated value, it is not easy for the user to find the unconformity so that deviation of the measured result is over large sometimes and causing hidden troubles in safety.
DIT-321 has test voltage of 250V / 500V / 1000V and can monitor the output high voltage in real-time. At any time, the user can observe actual measurement voltage that is delivered by the meter, effectively avoiding misjudgment caused due to output voltage not conforming to the rated value.

The measurement range of the meter can reach up to 40GΩ. The measurement time can be set up according to requirements. After a measurement is completed, the measured result can be saved automatically. Functions of the digital multimeter include AC/DC Voltage, AC/DC Current, Resistance, Capacitance, Frequency, Diode, and Continuity Measurement. The functions of the digital multimeter are completely separated from those of the Insulation Resistance Tester.

While using functions of the multimeter, you need not be worried that you would suffer electric shock due to high voltage generated by the insulation resistance tester. The product is used to measure the insulation resistance of various insulating materials and electric equipments such as Transformers, Motors, Cables, Switches, and Electric Apparatus. It is also applicable for maintenance, test, and inspection of various electric equipments. It is compact in structure, convenient to carry, and an ideal electrical and electronic testing meter.
