3.2.4 If you need data hold when measuring, you can put on “HOLD”, it will hold the reading;
if you put on the button again, data hold will not continue.
3.2.5 When only the figure “1” is displayed, it indicates overrange situation and the higher range
has to be selected.
3.3 TESTING DIODE/CONTINUITY
3.3.1 Connect the black test lead to the COM jack and the red test lead to the V/
Ω
jack.
(NOTE: The polarity of red lead connection is positive“
+
”)
3.3.2 Set the rotary switch at position and connect the red lead to the anode, the black lead to
the cathode of the diode under testing. The meter will show the approx. forward voltage drop of
the diode. If the lead connection is reversed, only figure “1” will be displayed. If continuity exists
(i.e. resistance less than about 70
Ω
), a built-in buzzer will sound.
3.4 MEASURING RESISTANCE
3.4.1 Connect the black test lead to the COM jack and the red test lead to the V/
Ω
jack.
(NOTE: The polarity of red lead connection is positive“ ”)
3.4.2 Set the rotary switch at desired
Ω
range position and connect test leads across the resistance
under measurement. Read the LCD display.
NOTE:
1. For resistance above 1M
Ω
, the meter may take a few seconds to stabilize reading.
2. When the input is not connected, i.e. at open circuit, the figure “1” will be displayed for the
overrange condition.
3. When checking in circuit resistance, be sure the circuit under test has all power removed and all
capacitors are full discharged.
4. At 200M
Ω
range display is 10 counts when test leads are shorted. These counts have to be
subtracted from measuring results. For example, when measuring 100M
Ω
resistance, the reading
will be 101.0 and the correct measuring result should be 101.0 - 1.0 = 100.0 M
Ω
.
3.5 TESTING BATTERY
3.5.1 Connect the black test lead to the COM jack and the red test lead to the V/
Ω
jack.
3.5.2 Set the rotary switch at the desired “BAT” range position and connect test leads across the
battery.
