Important Safety Information
Electric shock hazard:
• Do not expose this unit to rain or moisture.
• Do not use the unit if it is wet or damaged.
• Check test leads before use. They must be clean and dry, and the insulation must be in
good condition.
• Use this unit for the manufacturer's intended purpose only, as described in this manual.
Any other use can impair the protection provided by the unit.
Failure to observe these warnings could result in severe injury or death.
Electric shock hazard:
• Do not operate with the case or battery cover open.
• Before opening the case or battery cover, remove the test leads from the circuit and shut
off the unit.
Failure to observe these precautions may result in injury and can damage the instrument.
Electric shock hazard:
• Unless measuring voltage, shut off and lock out power. Make sure that all capacitors are
discharged. Voltage must not be present.
• Using this unit near equipment that generates electromagnetic interference can result in
unstable or inaccurate readings.
Failure to observe these warnings could result in severe injury or death.
Electric shock hazard:
• Do not change the measurement function while the test leads are connected to a
component or circuit.
• Do not use the meter to measure voltages in circuits that could be damaged by the Auto
V•Ω mode’s low input impedance (approximately 160 kΩ).
• Do not attempt to repair this unit. It contains no userserviceable parts.
• Do not expose the unit to extremes in temperature or high humidity. Refer to
“Specications.”
Failure to observe these precautions may result in injury and can damage the unit.
NOTE: The test leads of this unit are not removable. Do not attempt to remove them.

Electric shock hazard:
Contact with live circuits could result in severe injury
or death.
Electric shock hazard:
• Do not change the measurement function while the test leads are connected to a
component or circuit.
• Do not use the meter to measure voltages in circuits that could be damaged by the Auto
V•Ω mode’s low input impedance (approximately 160 kΩ).
Failure to observe these precautions may result in injury and can damage the unit.
Using the Features
• Low Impedance Auto V•Ω Mode In this mode, the meter automatically selects the
proper
measurement based on the input.
– If there is no input, “Auto” appears on the display.
– If voltage above approximately 2 volts AC or DC is present, voltage is displayed.
The meter
beeps once when switching from Auto to voltage measurement.
– If both AC and DC voltages are present, the larger voltage is displayed.
– If no voltage is present and there is resistance less than 6 MΩ, resistance is
displayed.
This mode features low input impedance to mask stray or “ghost” voltage pickup. The
input impedance is approximately 160 kΩ.
Overload Alert Feature: When above rated voltage is present (450 V), the meter
displays “OL”, with a warning beep tone. Disconnect the test leads from the voltage
source immediately.
Function Lock Feature: When a measurement is being displayed in Auto V•Ω mode,
pressing the button one time will lock in that function. Pressing the button again will
return the multimeter to Auto V•Ω mode. It is sometimes useful to “lock in” a function.
This may be helpful for measuring low voltages.
•Intelligent Automatic Power Off (APO) To extend battery life, the meter shuts itself
off after approximately 3 minutes of inactivity. Inactivity occurs when the selector
button is not pressed. The meter will not enter APO when there are signicant readings
over 10% of the range or non-OL readings for resistance and continuity.

Operation (cont’d)
1. Press and hold the selector button for 1 second to turn the meter on. The default
mode is
Auto V•Ω.
2. The Settings Table shows the meter’s functions. To change to the next function,
momentarily
press the selector button. Refer to “Typical Measurements” for specic
measurement
instructions.
3. Test the unit on a known functioning circuit or component.
• If the unit does not function as expected on a known functioning circuit, reset the
microprocessor by pressing and holding the selector button for 6 seconds.
• If the unit still does not function as expected, replace the battery.
• If the unit still does not function as expected, send the unit to Tempo for repair.
