Specifications are subject to change without notification.
Special attention should be paid when using the test and measurement
instrument because improper usage may cause electric shock and damage the
equipment.
– Use proper measurement category (CAT), voltage, and amperage rated probes,
test leads, and adapters for the measurement.
– Do not use or store the device around explosive gas, vapor, or under high
temperature and humidity.
– When handling the test probes and crocodile clips, keep your fingers behind
the physical guard.
– Examine the measuring test leads (if present) before use. Any element of
which the insulation deteriorates (even partially), replace them with proper
functional test leads.
– Connect the common test lead before the live test lead and remove the live
test lead before the common test lead.
– Before measuring current, make sure the instrument fuses available and
disconnect the power supply to the circuit test
– Remove the batteries if the device is not used for an extended period of
time, or if stored in temperatures above 45 °C. If the batteries are not
removed, battery leakage can damage the device.
