3. When the meter is not in use keep the meter turned off to keep the battery from discharging.
4. When disconnecting the test leads from the unit, always grasp the leads where the input jacks meet the tester
housing. Do not pull the leads out of the jacks by the insulated wire or transport the tester using the test leads as a
carrying strap.
5. Do not immerse the meter in water or solvents. To clean the housing use a damp cloth with a minimal amount of mild
soap.
NOTE: With any measurement made by this meter, there will be some fluctuation of the digital display. This is
due to the meter’s sampling method. This unit samples at a rate of 2 times per second, thus the fluctuation of
the readout.
3.0 FUNCTION BUTTONS
3.1 REL
∆
BUTTON
1. Press REL
∆
button to enter relative change mode and automatically enter manual ranging mode.
2. The present measurement value is saved as a stored value.
3. Take a second measurement and the meter will display the difference or change between the initial stored
measurement value and the new measurement value.
4. Pressing the REL button again or turning the rotary switch will exit the Relative mode and enter the normal
measurement mode.
Note: The meter can not enter the relative mode when it displays OL.
3.2 LOW IMPEDANCE BUTTON
WARNING
To avoid damage to the meter do not use this button when the measured voltage is higher than 250V. Do
not press this button for more than 3 seconds.
1. Press and hold Low imp. 400K
Ω
button to switch input impedance from 10M
Ω
to 400k
Ω
. Do not press this button for
more than 3 seconds.
2. When this button is released the meter returns to the default input impedance of 10M
Ω
3.3 AUTO OFF
1. To conserve battery life the meter powers off automatically after 15 minutes of non use.
To disable auto off press the select button while turning the meter on.

WARNING
To avoid personal injury or damage to the Meter, do not attempt to measure voltages higher than
750V AC.
4.1 AC VOLTS V~
There are four ranges for measuring AC voltage, 4V, 40V, 400V, 750V. For more accurate measurements use the lowest
setting possible without exceeding the voltage setting. Ie. Use the 4V setting only if the voltage is 4V or less.
1. Set the function/range switch to V~.
2. Insert the black test lead into the COM input terminal.
3. Insert the red test lead into the V input terminal.
4. Touch the test leads to the circuit under test. With AC voltage, the polarity of the test leads is not a factor.
NOTE: It is best to touch one of the test leads to ground or Neutral first and then touch the 2nd test lead to the
hot wire.
5. Read the value of the measurement displayed.
6. Typical AC Voltage measurements include wall outlets, appliance outlets, motors, light fixtures and switches.
