fuse. When measuring, if the meter has no reading display, please check relevant fuse.
2.9 Resistance Measurement
1. Apply the black test lead to "COM" terminal and the red test lead to “V/Ω” terminal.
2. Set the knob to a proper resistance range, and connect the leads crossly to the resistance under test.
Note
:
1. The LCD displays "1" when the resistance is over the selected range. The knob should be adjusted to a higher range. When
resistance under test is over 1MΩ, the reading shall be stable in a few seconds, which is a normal status when measuring high
resistance.
2. When the input terminal is in open circuit, it displays overload.
3. When measuring in line resistor, be sure that the power is off and all capacitors are released completely.
4. It is absolutely forbidden to input voltage at the range of resistance, though the meter has voltage protection function at this
range.
2.10 Diode Test
1. Apply the black test lead to "COM" terminal and the red lead to "V/Ω" terminal (the polarity of red lead is “+”)
2. Set the knob to
“
”
range, connect test leads to the diode under test. The red test lead connects to diode positive polarity
and the reading is the approx. value of diode forward voltage drop.
2.11Continuity Test
Set the knob to
“
”
range, apply test leads to the two points of tested circuit. If the inner buzzer sounds, the resistance is less
than (70±20) Ω.
4. Maintenance
This is a precise meter; please don't try to modify the circuit.
Note
:
1. Do not input voltage over DC600V or AC 600Vrms.
2. Do not measure voltage on range Ω.
3. Do not use this meter for measurement if the battery is not correctly placed or the back case is not properly screwed.
4. Remove the test leads from the testing points and turn off the meter before replacing battery or fuse.
Battery Replacement
Note
: Pay attention to the battery status.
Please replace the battery when LCD displays “
”
.
Steps:
1. Unscrew the battery cover.
2. Take out the 9V battery and replace it with a new one.
3. Install and screw the battery cover.
Fuse Replacement
(This operation could only be processed in power off status.)
1. Unscrew the battery cover.
2. Take out the battery and open the back cover.
3. Please use fuse of the same specification.
