Maintenance
This Multimeter is designed to provide years of dependable service,
if the following care instructions are performed:
1. KEEP THE METER DRY. If it gets wet, wipe it off.
2. USE AND STORE THE METER IN NORMAL TEMPERATURES. Temperature
extremes can shorten the life of the electronic parts and distort or melt
plastic parts.
3. HANDLE THE METER GENTLY AND CAREFULLY. Dropping it can damage the
electronic parts or the case.
4. KEEP THE METER CLEAN. Wipe the case occasionally with a damp cloth.
DO NOT use chemicals, cleaning solvents, or detergents.
5. USE ONLY FRESH BATTERIES OF THE RECOMMENDED SIZE AND TYPE.
Remove old or weak batteries so they do not leak and damage the unit.
6. IF THE METER IS TO BE STORED FOR A LONG PERIOD OF TIME, the batteries
should be removed to prevent damage to the unit.

Operation
AC/DC Voltage Measurements
1. Set the rotary function switch to the
V Hz% position.
2. Press the button to select AC or DC
voltage.
3. Connect the test leads in parallel to the
circuit under test. For DC measurements
touch the red test probe to the positive side
of the circuit and the black test probe to the
negative side of the current.
4. Read the voltage on the LCD display
AC/DC Current Measurements

1. For current measurements up to 200mA AC/DC,
set the rotary function switch to the mA position.
2. For current measurements up to 4000µA AC/DC,
set the rotary function switch to the µA position.
3. Press the button to select AC or DC current.
4. Remove power from the circuit under test,
then open up the circuit at the point where
you wish to measure current.
5. Touch the test probe tips in series with the
circuit being measured. For DC current,
touch the black test probe to the negative
side of the circuit and touch the red test
probe to the positive side of the circuit.

Non-contact AC Voltage Detection
(Detection range 100 to 600V)
Risk of Electrocution. Before use, always test the Voltage
Detector on a known live circuit to verify proper operation.
WARNING:
1. Hold the detector probe tip close to an AC voltage.
2. If AC voltage within the specified range
is present, the indicator light will illuminate.
NOTE: Insulation type and thickness, and
distance from the voltage source and other
factors may effect operation. Use other methods
to verify live voltage if there is any uncertainty.
NOTE: The detector is designed with high
sensitivity. Static electricity or other sources
of energy may randomly trip the sensor.
This is normal operation.
