Datasheet

The Quadtech 1868A Megohmmeter is a resistance and current measurement instrument with an insulation resistance testing capacity of 10kΩ to 1PΩ at DC test voltages ranging from 10 to 1000V or 50 to 5000V. This device also provides a powerful charge current of up to 80mA to charge high capacitive devices, possesses a basic accuracy of ± 2% to 1TΩ and features five programmable limit sets. Program your Quadtech 1868A to your desired charge, delay and discharge settings and choose from one of four testing ranges or activate automatic ranging. Technicians can store four test sets in this device, which displays data via remote I/O, RES232 and IEEE-488.2 interfaces for remote control operation and communication with other devices. Rent the Quadtech 1868A to test insulation, capacitive components and connection resistance.
