Data Hold
XW Warning
To prevent possible electrical shock, fire or personal injury, do not use the HOLD
function to measure unknown potentials. When HOLD is turned on, the display
does not change when a different potential is measured.
To hold the present reading, push
H. Push H again to resume normal operation.
Measure AC and DC Voltage
To measure ac and dc voltage:
1. Choose ac or dc by turning the rotary switch to
K
,
L,
or G.
2. Connect the red test lead to the J terminal and the black test lead to the COM
terminal.
3. Measure the voltage by touching the probes to the correct test points of the circuit.
4. Read the measured voltage on the display.

Measure Resistance
1. Turn the rotary switch to
D. Make sure power is disconnected from the circuit to be
measured.
2. Connect the red test lead to the J terminal and the black test lead to the COM
terminal.
3. Measure the resistance by touching the probes to the desired test points of the circuit.
4. Read the measured resistance on the display.
Test for Continuity
With the resistance mode selected, push the YELLOW button once to activate the continuity
mode. If the resistance is <70 Ω, the beeper sounds continuously, designating a short circuit.
If the Product reads
o
, the circuit is open.

Test Diodes
1. Turn the rotary switch to
D.
2. Push the YELLOW button twice to activate the diode test mode.
3. Connect the red test lead to the J terminal and the black test lead to the COM
terminal.
4. Connect the red probe to the anode and the black test lead to the cathode of the diode
being tested.
5. Read the forward bias voltage value on the display.
6. If the polarity of the test leads is reversed with diode polarity, the display reading shows
o. This can be used to distinguish the anode and cathode sides of a diode.
Measure Capacitance
1. Turn the rotary switch to
c.
2. Connect the red test lead to the J terminal and the black test lead to the COM
terminal.
3. Touch the probes to the capacitor leads.
4. Let the reading stabilize (up to 18 seconds).
5. Read the capacitance value on the display.

Measure Frequency and Duty Cycle
To measure frequency:
1. Turn the rotary switch to
I
.
2. Connect the red test lead to the J terminal and the black test lead to COM
terminal.
3. Measure frequency by touching the probes to the correct test points of the circuit.
4. Read the frequency on the display.
To measure duty cycle:
1. Turn the rotary switch to
