MEASURING METHODS
BEFORE PROCEEDING MEASUREMENT, READ SAFETY NOTES ON PAGE 3.
1. Ensure the system under test is not live.
2.
In proceeding with measurement, if ”
”
symbol appears on the
display, replace with new batteries.
3. Short the tips of the leads. Adjust the 0
Ω
.ADJ control to set the reading of
zero.
4. Rotary the function switch to suitable range then press the pushbutton to
test and take the reading.
5. A drawing of the system should be made before testing so the
measurement can be attributed to network.
6. Measure system power-an 10W up.
P=ZI2
P=V2 I Z
For example on a 100V system:
If P=50W Z=V2 I P=1002 I50=200
(1) The tester can measure load down to 2k
Ω
.(10W at
100V line).
(2)
The tester can’t
measure 100V system with power lower than 10W.
