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.

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.

Range Guide for Ohms (Ω):

300 = Meter indicates actual resistance
3k = Multiply meter display reading by 1,000 to

acquire actual resistance.

30k = Multiply meter display reading by 1,000 to

acquire actual resistance.

300k = Multiply meter display reading by 1,000 to

acquire actual resistance.

3M = Multiply meter display reading by

1,000,000 to acquire actual resistance

300M= Multiply meter display reading by

1,000,000 to acquire actual resistance.
The meter displays total resistance through all possi­ble paths between the probe-tips. These multiple
paths may result in measurements that do not corre­spond to the ohm value indicated by the resistor
color code.

Determining Resistor Values:

To determine the value of a resistor, use the color bands on the

resistor and the table on the following page.

Diode Check:

To ensure a proper functioning diode, the meter will develop a
voltage across the component from a test current. The diode
test function allows measurements of forward voltage drops
across diode and transistor junctions.

1. Turn off power to the device or circuit that is being tested
and discharge all capacitors.

2. Plug the black test lead into the COM port and the red test
lead into the VΩHz port.

3. Set the rotary switch to the Ω position.

4. Press the blue button until is shown on the display

5. Connect the test leads to the diode. Normally the forward
voltage drop of a good silicone diode is shown between
400V and 90V. If the diode under test is defective, “000”
(short circuit) or “OL” (non-conductive) is displayed.

between the case and battery cover before replacing the
battery cover and screw.

Fuse Replacement

1. Remove the test leads from the front terminals and turn the
meter off.

2. Remove the screw from the battery cover and lift to remove.

3. Remove the screws from the bottom case and the inside of
the battery cover and lift the case bottom until it unsnaps
