WARNING!
1. DO NOT UNDER ANY CIRCUMSTANCES EXCEED THESE
RATINGS:
• Voltage is not to exceed 1000 Volts.
• Resistance, Capacitance, Logic and Continuity functions
are not to be performed on circuits capable of delivering
greater than 600 Volts.
• Current measurements are not to be performed on cir-
cuits capable of delivering greater than 500 Volts
2. To avoid electrical shock hazards and/or damage to the meter:
• Do not exceed the voltage ratings for the meter. Use
caution when measuring voltage.
• Do not use during electrical storms. AC power sources
with inductive loads or electrical storms may result in
high voltage. High energy transients can damage meter
and present a dangerous shock hazard.
• Turn off power to the circuit or device being measured
before taking resistance and capacitance measurements.
Fully discharge all capacitors before measuring.
3. Ensure meter is in proper working order before using.
Visually inspect meter for damage. Performing a continuity
check can verify proper operation. If the meter reading goes
from overload to zero, this typically means the meter is in
proper working order.
4. Visually inspect leads for damage before using. Replace if
insulation is damaged or leads appear suspect.
5. Never ground yourself when taking electrical measurements.
Do not touch exposed metal pipes, outlets, fixtures etc.
Keep your body isolated from ground by using dry clothing,
rubber shoes, mats, or any other approved insulating material. Keep your fingers behind the finger guards on the
probes. Work with others.
6. Before beginning all unknown measurements, set meter to
highest possible range.
7. Before breaking a circuit for testing, turn off the power to the
circuit. When disconnecting from a circuit, disconnect the
hot lead first, then the common lead.
8. Disconnect the meter from the circuit before turning off any
indicator, including motors, transformers, and solenoids.

1. Digital Display - The digital display has 3400 counts
LCD readout with 70 segments analog bar graph, auto
polarity, decimal point, “ “ AC, DC RANGE, HOLD
APO and unit annunciators.
2. Rotar y Switch - Select the Function and Range desired.
3. COM Input Terminal -Ground input connector.
4. VΩHz Input Terminal - Positive input connector for
Volts, Ohms and Frequency.
5. mA Input Terminal - Positive input connector for Amp
measurements (up to 340mA).
6. A Input Terminal - Positive input connector for Amp
measurements (up to 10A).
7. Range Switch, (Manual Range) - “range” switch is
pushed to select manual ranging and to change ranges.
When “Range” switch is pushed on “Range” annunciator on
the LCD appears. Push “ RANGE ” switch to select appropriate range to be used. Push “Range” switch and hold 2
seconds to return to Autoranging.
8. Blue Switch - Push to switch to measure AC
Voltage/Current or DC Voltage/Current in the
Voltage/Current mode or to measure Resistance or continuity or diode in Ω/ / mode.
9. Hold Switch - This switch is used to hold measured value
for all functions, and then “HOLD” annunciator is displayed.
Conversions are made but the display is not updated.
10. Hz Switch - This switch is used to quickly view the
frequency during measuring the AC voltage or current.
Push “ Hz” switch once the LCD is changed to display
frequency. Push “ Hz” switch again, the LCD back to
display the AC signal amplitude reading. In “ Hz” mode,
pressing RANGE key switch does not change the frequency
range. However, RANGE key switch changes the sensitivity
of frequency detection, if the input signal amplitude is less
than 1% of full scale reading, the user shall increase the
sensitivity. Pressing Range switch in “ Hz” mode also
changes the full scale range of the original voltage or current mode.

Input Impedance: 10MΩ less tan 100PF.
To Measure True RMS AC Voltage:
1. Plug the black test lead into the COM port and the red test
lead into the VΩHz port.
2. Set the rotary switch to the V position.
3. Push the blue button until AC is shown on the display.
4. Connect the meter in parallel with the load or circuit.
5. Measure AC Voltage.

Unit of Measure Multipliers
For your reference, the following symbols are often used to
make measurement easier:
Symbol Verbal Multiplier
M mega x 1,000,000
k kilo x 1,000
m milli ÷1,000
µ micro ÷ 1,000,000
Auto Power Off (APO)
The APO sign on the LCD panel indicates the meter is working
in the Auto Power Off mode. If the meter idles for more than 10
minutes, the meter automatically turns the power off. When this
happens, the state of the meter is saved the meter can be
turned back on by pushing any key switch or changing the
rotary mode. The meter will give an alarm 15 seconds before
the meter automatically turns the power off. To disable the auto
power off function, power-up the meter while pressing either
the range or Hz switch.
Hz sensitivity
The sensitivity in the Hz mode (pushing key) is 1/10 of full
scale range. The accuracy is same as Frequency mode. The
measuring frequency is from 40Hz up to 1KHz.
