Overview This instrument adopts a LCD monitor with backlight, so that the values can be clearly read even at a dark piace. lt is a compact handheld digital multimeter (4000 counts) with high performance and reliability. lt uses integrate circuit and A/D converter as the core,...
measured range is unknown size.Keep test pen from the circuit under test before the function range is switched. Power off the circuit and discharge all the capacitors before in-circuit resistance measuring. Please be careful to put your fingers beyond the hand-blocking part of test pen when measuring voltage over...

3. How to Use 3.1 Precautions for operation: 1. Power on and check whether the battery ìs under voltage or not. lf the symbol is displayed, the battery needs to be replaced; otherwise, please follow the following steps. 2. The warning symbol next test...
3.3 AC voltage measurement insert the red probe into jack and the black probe into jack"COM" 2. Set function range switch the range and connect the test pen power supply or load to be measured. The measured value will be displayed on the screen.
Attention 1. lt shows an overrange state when the measured resistance exceeds the maximum value in the selected range. In this case, a higher range OL should be selected. The readings may keep stable in a few seconds when measuring resistance above 1M. lt's normal for high resistance measurements.
1. Check and confirm that the test pen has kept off the circuit under test, in order to avoid electric shock. 2. Check and confirm that the rear cover is tightly fixed before use. 4. Maintenance Keep the test pen away from circuit under test before opening...
1. Measurement range: 80V-600V AC, S0Hz or 60Hz. Voltage may exist in use even when there is no sound or light alarm. The instrument may fail to sense the electric field due to other factors such as shielded wire and cable, thickness insulating layer,...
