Figure3-5.TC Measurement
The temperature degree is shown on the primary display, the TC value on the secondary display and Fahrenheit degree on
elapsed time display.
When the output jack is open circuit, the screen displays OL.
Warning
To avoid possible electric shock or personal injury, do not connect the TC with the
live circuit.
Measuring Resistance (See Figure3-6)
Warning
To avoid possible damage to the meter or to the equipment under test,
disconnect circuit power and discharge all high-voltage capacitors before
measuring resistance.
The meter’s
resistance ranges are400.0

To measure resistance, proceed as follows:
1. Set the rotary switch to
position (Default value in this function)
2. Insert the black lead into “
COM
” terminal, and the red lead to into the “
Ω
V
” terminal.
3. Connect the leads to the tested power.
4. Read the measuring results from the screen.
Caution
“OL” appears on the display if the resistance under test is open or the value surpasses the maxim range.
The test lead can add 0.1
Ω
to 0.2
Ω
of error to resistance measurements. To test the leads, touch the probe tips
together and read the resistance of the leads.
If necessary, you can press
to automatically subtract this value.
Wait for several seconds for stable reading when measuring resistance more than 1M
Ω
.
