Varistor Tester

The HM6020 varistor tester is a fully automatic zinc oxide measurement product, which has the functions of measuring the initial operating voltage U (1-10mA) and the leakage current I0.75U and I0.5U.

● Designed in strict accordance with safety standards

● With voltage limit function

● Automatically cut off the output voltage after measurement

● 2 kinds of power supply methods: use lithium ion battery to supply power, and can be charged in use state at the same time. In the event of a power failure, it can automatically switch from AC power to battery power.

● All English display, Chinese prompt operation, simple and clear, and can display the insulation resistance simulation column.

The design, manufacturing and testing of this instrument have reached the IEC61010 safety standard (safety requirements for electronic measurement products). This manual includes the warnings and safety regulations that must be followed by the user to ensure the safe use of the instrument and the safe state of the instrument. Please read the following instructions before use.

● The instrument outputs high voltage. Before use, read and understａnd the operation guide in the manual.

● Please keep the manual with you for easy reference at any time.

● The instrument must be used as directed.

● Understａnd and follow the safe operation instructions.

The above operating instructions must be strictly followed.

Failure to observe this may result in personal injury and damage to the instrument during measurement.

Dangerous (indicating that improper operation can cause serious or fatal injuries)

● Please wear insulated gloves before use.

● Do not measure in a circuit above AC/DC600V.

● Do not test in flammable places, sparks may cause an explosion.

● Do not operate when the surface of the instrument is wet or the operator's hands are wet.

● Please do not connect the test lead with power.

● Do not touch the circuit under test immediately during or after the test, as it may cause electric shock.

● Please stop the test when any dirt or charcoal that easily damages the insulation characteristics is found on the test line or terminal.

Warning (indicating that improper operation may cause serious or fatal injury)

● If the instrument is abnormal, please stop using it. For example: the instrument is damaged or exposed metal parts.

● Please do not install substitute parts or make any unauthorized modification to the instrument. Please contact our company for maintenance.

● Make sure that all test leads are firmly connected to the test ports of the meter.

Attention (means improper operation may cause personal injury or damage to the instrument)

²Before measurement, confirm that the voltage is selected at an appropriate value.

² If the battery is not used for a long time, the battery should be fully charged and stored, and refilled within three months.

² Do not place it for a long time in a place with high temperature, humidity, condensation possibility and direct sunlight.

²Please use a damp cloth or detergent to clean the case of the instrument, do not use abrasives or solvents.

²When the instrument is wet, please dry it before storing.
