MS8218 True RMS Multimeter
Operation Methods
Resistance/continuity Test
The test chart is seen in Figure 3-6. the measurement range of resistance is of 0.01
Ω～
50M
Ω
and the measurement
methods are as follows:
1.
Turn on the power switch and set the rotary switch to the position .
2.
Insert the red and black testing lines into the
V
Ω
Ω
Ω
Ω
H
input end and the
COM
input end respectively.
3.
Press the
SELECT
key to select resistance (
Ω
Ω
Ω
Ω
) or the continuity ( ) modes.
4.
For the resistance measurement, connect the red and black probes to the two ends of resistor and read the resistance
value from the display screen. If OL displaying, it indicates the resistor is larger than 50M
Ω
. As for the continuity
measurement, connect the red and black probes to the two measured points respectively. In case of the resistance
between the two points being less than about 50
Ω∽
60
Ω
, the buzzer will sound while the display screen displaying the
value of resistance. If OL displaying, it indicates the resistance between the two points is larger than 500
Ω
.
5.
When the resistance measurement mode being implemented, it is possible to select range by pressing the RANGE key.
The indicator of range indicates the value of range. If OL displaying during manual range measurement, it is necessary
to select a larger range. Under the continuity measurement mode it is null to press the
RANGE
key.
Notes: In case of performing resistance or continuity test on circuit board, it is necessary firstly to turn off the power of the
circuit board and then perform the measurement. As there may be other parallel circuits, so the displayed value of test is not
surely the actual value of the resistor.
