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.

Auto Power Off (APO)
The APO sign on the LCD panel indicates the meter is working
in the Auto Power Off mode. If the meter idles for more than 30
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 key
switch or changing the rotary switch. The meter will give an
alarm in 15 seconds before the meter automatically turns the
power off. To disable the auto power off function, power up the
meter while pressing either the range, REL or min/max
switch.

Range Guide for Ohms (Ω):
400 = Meter indicates actual resistance
4k = Multiply meter display reading by 1,000 to
acquire actual resistance.
40k = Multiply meter display reading by 1,000 to
acquire actual resistance.
400k = Multiply meter display reading by 1,000 to
acquire actual resistance.
4M = Multiply meter display reading by
1,000,000 to acquire actual resistance
400M= Multiply meter display reading by
1,000,000 to acquire actual resistance.
The meter displays total resistance through all possi-
ble paths between the probe-tips. These multiple
paths may result in measurements that do not corre-
spond to the ohm value indicated by the resistor
color code.
Determining Resistor Values:
To determine the value of a resistor, use the color bands on the
resistor and the table on the following page.

Gray 8 8 100,000,000
White 9 9 1,000,000,000
Gold +/- 5%
Silver +/- 10%
No Color +/- 20%
Example:
1st color band is blue so the first digit is a 6
2nd color band is red so the second digit is a 2
3rd color band is yellow so multiply 62 x 10,000
4th color band is gold so the tolerance is ±5%
Your Resistor value is 620,000 Ohms (620kΩ) with a tolerance
of ±5%.

Diode Check:
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 diode and transistor junctions.
1. Turn off power to the device or circuit that is being tested
and discharge all capacitors.
2. Plug the black test lead into the COM port and the red test
lead into the °C°F VΩHz port.
3. Set the rotary switch to the Ωposition.
4. Press the blue button until is shown on the display
5. Connect the test leads to the diode. Normally the forward
voltage drop of a good silicone diode is shown between
400V and 90V. If the diode under test is defective, “000”
(short circuit) or “OL” (non-conductive) is displayed.
