WARNING!
1. DO NOT UNDER ANY CIRCUMSTANCES EXCEED
THESE RATINGS:
- Voltage is not to exceed 600V AC or DC.
- Resistance, Capacitance, Logic, and Continuity
functions are not to be performed on circuits capable
of delivering greater than 500V AC or DC.
- Current measurements are not to be performed on
circuits capable of delivering greater than 600V AC
on insulated conductors, 250V AC on uninsulated
conductors.
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 the 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, rubber 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 the highest range possible.

To Measure Resistance:
Resistance is measured in Ohms.
1. Turn the power off to the circuit or device that is to be measured and discharge all capacitors before measurement is
to be taken.
2. Plug test leads into the meter inputs as indicated in the
following diagram.
3. Select the proper range within the Ω function of the tester.
4. Measure resistance. If necessary, perform the required
multiplication to acquire the actual resistance.
4.1 Range Guide for Ohms (Ω):
200 = Meter indicates actual resistance
2K = Multiply meter display reading by 1,000 to
acquire actual resistance.
20K = Multiply meter display reading by 1,000 to
acquire actual resistance.
200K = Multiply meter display reading by 1,000 to
acquire actual resistance.
2M = Multiply meter display reading by
1,000,000 to acquire actual resistance
200M = Multiply meter display reading by
1,000,000 to acquire actual resistance.
5. The meter displays total resistance through all possi-
ble 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.

Diode Testing:
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 diodes and transistor junctions.
1. Turn off power to the device or circuit that is being tested
and discharge all capacitors.
2. Plug the leads into the meter inputs as indicated in the following diagram.
3. Select the diode function on the meter.
4. Connect the red rest probe to the anode (+) and the black
test probe to the cathode (-) of the diode. If the diode is
shunted by a resistor of 1K Ohm or less, it must be
removed from the circuit before taking the measurement.
