Note: When measuring ACV under auto range mode, pressing the RANGE key will display AC mV
range.
4. Connect the leads in parallel across the electric circuit under test, LCD displays voltage as measured
by the test leads.
Note:
1. Operator should first set the selector knob to the highest range, if operator has no idea about the
range of voltage under test, then select the proper range based on displayed value. If the LCD displays
'
OL
'
, it means the meter is over the maximum value of this range, select a higher range.
2
.
Never input a voltage over 750VAC.
3. Be careful while measuring a high voltage. DO NOT touch the high voltage circuit or leads.
4-4. DCA measurement
1.
Insert the black test lead into the
'
COM
'
terminal and the red one into the mA terminal (the Max.
400mA) or into the 20A terminal (the Max.20A).
2.
Use the selector knob and set to the proper DCA range, press the DC/AC key to select the
measurement mode. Then, connect the leads in series into the electric circuit under test. LCD
displays current under test.
3.
When measuring mA DC through a control jack, use the FS01 adapter between the meter leads and
the control jack. Insertion of leads into adapter is not important. If reading comes back as negative
(
─
) leads are reversed.
Note:
1.
Operator should first set the selector knob to the highest range, if operator has no idea about the
range of current under test, then select the proper range based on the displayed value .
2.
If the LCD displays
'
OL
'
, it means the current is over range. You need to move the selector knob to
a higher range.
3.
Maximum input current is 400mA or 20A based on the terminal the red test lead is inserted into,
too large a current will damage the meter.
4-5. ACA measurement
1. Insert the black test lead into the COM terminal and the red one into the mA terminal (maximum
400mA) or into the 20A terminal (maximum 20A).
2. Use the selector knob to set the proper ACA range, press the DC/AC key to select the measurement
mode, then connect the leads in series to the electric circuit under test. LCD displays current under test.
Note:
1. Operator should first set the selector knob to the highest range, if operator has no idea about the
range of current under test, then select the proper range based on the displayed value.
2. If the LCD displays
'
OL
'
, it means the current is over range. You need to select a higher range.
3. Maximum input current is 400mA or 20A based on the terminal the red test lead is inserted into, too
large a current will damage the meter.
4-6. Resistance measurement
1. Insert the black lest lead into the
'
COM
'
terminal and the red lead into the
'
V/
Ω
/Hz
'
terminal.
2. Turn the selector knob to
Ω
range.
3. Connect the leads in parallel with the resistance being measured.
3. Auto range is the original mode, press the RANGE key change to the manual range mode.
4. When measuring the actual minimum resistance, short-circuit the test leads first, press the REL
button and then test the resistance, it will now display the actual resistance.
