Operation
Voltage Measurements
1. Slide
the
Off/On/Hold
switch to the
ON
position.
2. Slide
the
V/A/
Ω
switch to the
V
position.
3. Connect the red test lead to the
V
input terminal and the black test lead to the
COM
input terminal.
4. If the voltage to be measured is AC, slide the
AC/DC
switch to the
AC
position.
5. If the voltage to be measured is DC , slide the
AC/DC
switch to the
DC
position
6. Connect test lead probes to the circuit under test.
7. Read voltage values on the LCD.
Resistance Measurements
1. Slide
the
Off/On/Hold
switch to the
ON
position.
2. Slide
the
V/A/
Ω
switch to the
Ω
position.
3. Connect the red test lead to the
Ω
input terminal and the black test lead to the
COM
input terminal.
4. If the resistance being measured is in a circuit, remove all power to that circuit and
discharge all capacitors.
5. Connect test lead probes to the circuit (resistance) under test.
6. Read the resistance values on the LCD.
Note: There are small stray resistances (approx. 0.8 ohms) in the test leads. Before
taking measurements short the test leads and note the meter reading. After taking a
measurement, deduct the stray resistance value (noted earlier) from the displayed
reading.
AC Current Measurements
1. Slide
the
Off/On/Hold
switch to the
ON
position.
2. Slide
the
V/A/
Ω
switch to the
A
position.
3. Slide
the
AC/DC
switch to the
AC
position.
4. Determine the highest anticipated current (200A, 20A)
and set the
20A/200A
switch to the appropriate position.
5. Press the trigger to open the current jaw. Clamp around
the conductor under test.
6. Read ACA values on the digital display.
DC Current Measurements
1. Slide
the
Off/On/Hold
switch to the
ON
position.
2. Slide the V/A/
Ω
switch to the
A
position
3. Slide
the
AC/DC
switch to the
DC
position.
4. Slide
the
20A/200A
switch to the
200A
position.
5. Adjust the DCA Zero knob for a zero reading.
6. Press the trigger to open the current jaw. Clamp around the conductor under test.
7. Read DCA values on the digital display.
