Feature:1. Color LCD display, the first 1V ~ 1000V arbitrary voltage output, to meet any critical requirements.2. 6-range test, the insulation resistance measurement range can reach: 100k-10T (105~1013), the maximum display digit is 20000. 3. With a test speed of up to 100 times per second, ultra-high speed testing provides the best solution for automated production. 4. AT688 insulation resistance tester is an intelligent test instrument controlled by a high performance ARM microprocessor. 5. The instrument has sorting function, sorting the sound setting, and can also be equipped with a Handler interface, which is applied to the automatic sorting system to complete the automatic pipeline test.6. It can be equipped with RS232C interface for remote control and data acquisition and analysis.7. Computer remote control instruction is compatible with SCPI (Standard Command for Programmable Instrument Standard Command set), and completes remote control and data acquisition functions efficiently.8. Application fields: Used for field test or timed test and destructive test. Test insulation resistance and leakage current of switchgear, relays, motors, generators and cables. Measurement of insulation resistance of electronic components and equipment.
