Description of Handheld Digital Insulation Tester

PM1508 is a digital insulation resistance tester powered by battery. It is controlled by microprocessor chip and has high precision, stability and reliability. The insulation resistance measurement has 5 range test voltage output, the maximum insulation resistance measurement is 100GΩ, and the basic accuracy can reach ± 1.5%, which can meet more application test needs of customers. In addition to insulation measurements, ACV, DCV, frequency and low resistance measurements can be performed. It is mainly used in transformer, motor, generator, cable, electrical and other electrical equipment and insulation material measurement. The design is exquisite, durable and easy to operate, making it an ideal tool for many occasions of maintenance, debugging and preventive maintenance.

TEST – In the insulation resistance test mode, when the LOCK function is on, press the “TEST” key to start/end the test. When the LOCK function is not on, press and hold the “TEST” key and keep measuring, and release the key to end the measurement.
HOLD – In the non-insulation test mode, press the “HOLD” key to enter/exit the reading holding mode. In the insulation resistance test mode, when a single measurement ends, the HOLD mode will be automatically activated. Press the key to exit HOLD mode.
LOCK – The function is only valid in insulation resistance measurement mode. Press this key to turn on/off the LOCK function. In the process of insulation resistance measurement, press the key to end the measurement.
