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
circuits 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. Min/Max Switch
• Pressing this button once results in the displayed maximum value of the current reading.
• Pressing the min/max button once more results in the
displayed minimum value of the current reading.
• If pressed a third time “Max Min” will flash on the LCD
indicating that the minimum and maximum value are
being recorded while the current reading is displayed.
• Pressing the min/max button for > 2 seconds exits the
Min/Max mode.
2. Range Button
• Pressing the range button selects the manual ranging
mode.
• When the range button is pressed RANGE will
appear in the upper left of the LCD display.
• WHen in the manual range mode, pressing the range
button changes the measurement range.
• To return to auto ranging, hold the range button for >2
seconds.
3. Hold Button
• The hold button is used to hold the measured value for
all functions.
• The value is displayed alon g with the annunciator.
• This function can be used in the min/max or peak
min/max mode.
Auto Power Off (APO)
If the meter is left idle for more than 10 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 button 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 wile pressing
either the range or min/max button. To enable the auto power
off, switch the meter off and then on again without depressing
any buttons.

To Measure AC Voltage:
1. Plug the black test lead into the COM port and the red test
lead into the Hz V Ω µA port.
2. Set the rotary switch to the v position.
3. Connect the meter in parallel with the load or circuit.
4. Measure AC Voltage.
