1. Digital Display – The digital display has 4000 counts

LCD readout with 82 segments analog bar graph, auto
polarity, decimal point, “ ” AC, DC RANGE,
APO and unit annunciators.

2. Rotary 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 400mA).

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 the 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 or to measure frequency or RPM in
Hz/RPM mode.

9. Hold Switch – This switch is used to hold measured value
for all functions, and then annunciator is displayed.
Conversions are made but the display is not updated. This
switch could be invoked to “MIN/MAX” mode or
“PMIN/PMAX” mode.

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.

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.

Unit of Measure Multipliers

For your reference, the following symbols are often used to
make measurement easier:

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 30
minutes, the meter automatically turns the power off. When this
happens, the state (non-logic measurement) of the meter is
saved, the meter can be turned back on by pushing any key
switch or changing the rotary switch. 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.

AC Conversion Type:AC conversions are ac-coupled, true rms
responding, calibrated to the rms value Sine wave input.

Input and Impedance: 10MΩ less than 100 PF.
Crest Factor: +1.5% additional error for C.F. from 1.4 to 3

+3.0% additional error for C.F. from 3 to 4

To Measure True RMS AC Voltage:

1. Plug the black test lead into the COM port and the red test lead
into the VΩH 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.
