2. AC VOLTAGE MEASUREMENT ˜V (See Figure 4)
(1) Insert test leads
- Insert the black test lead into the
COM input and the red test lead into the ˜V input.
(2) Set ˜V function
- Turn the dial to the ˜V
function.
(3) Test & Measure
- Place the red and black test leads at both the positive and negative points to be
measured. The clamp meter will automatically select the proper range and the display will show the True
RMS value of the measurement being taken while the slave display shows the frequency value of the AC
voltage.
Note: When measuring AC voltage below 500Hz, set the dial to the ˜V + Lo . This is the low pass filter, it
will filter high-frequency interference caused by frequencies above 7.5KHz to ensure a stable reading.
AC voltage measurement should not exceed 750V AC!
3. RESISTANCE MEASUREMENT
Ω
(See Figure 5)
(1) Insert test leads
- Insert the black test lead into the
COM input and the red test lead into the
Ω
input.
(2) Set
Ω
function
- Turn the dial to the
Ω
function.
(3) Select Function
- There are a total of 3 functions that are accessible by pressing the
SELECT key.
The Ohms function is the default option.
(4) Test & Measure
- Place the red and black test leads at both the positive and negative points to be
measured. The clamp meter will automatically select the proper range and the display will show
the resistance value of the measurement being taken on the display. When the test leads are not
connected or the resistance value is to great, the display will show an over-range symbol “
OL”.
When measuring resistance, the circuit should be powered off and all capacitors
should be completely discharged prior to testing. A more accurate measurement can be achieved by
separating the component from the circuit being tested.
4. DIODE MEASUREMENT
(See Figure 6)
(1) Insert test leads
- Insert the black test lead into the
COM input and the red test lead into the “
Ω
”
input.
(2) Set
Ω
function
- Turn the dial to the
Ω
function.
(3) Selection Function
- There are a total of 3 functions that are accessible by pressing the
SELECT key.
Press the
SELECT key until the
appears on the display.
(4) Test & Measure
- For forward voltage drop readings on any semiconductor component, place the
red test lead on the components anode and place the black test lead on the components cathode.
When the test leads are not connected or are reversed, the display will show an over-range symbol
“
OL”.
When measuring resistance, the circuit should be powered off and all capacitors
should be completely discharged prior to testing. A more accurate measurement can be achieved by
separating the component from the circuit being tested.
5. CONTINUITY
(See Figure 7)
(1) Insert test leads
- Insert the black test lead into the
COM input and the red test lead into the “
Ω
”
input.
(2) Set
Ω
function
- Turn the dial to the
Ω
function.
(3) Select Function
- There are a total of 3 functions that are accessible by pressing the
SELECT key.
Press the
SELECT key until the
appears on the display.
(4) Test & Measure
- Place the red and black test leads at both the positive and negative points to
be measured. The buzzer will sound when the resistance is less than 30
Ω
.When the test leads are
not connected or the resistance value is to greater than 100
Ω
, the display will show an over-range
symbol “
OL” and the buzzer will remain silent.
When measuring continuity, all power to the circuit or cable being tested
MUST be
turned off to prevent damage to the user or the clamp meter.
