personal computer (PC). This information can then be stored by filename in you PC and is
always accessible for any changes you may want to make the machine in the future, including
pricing. To load CHIP from your PC requires harness (P/N 17500004), included in this package.
Touch Memory Button (CHIP) and Upload/download Harness (P/N 16800013)
The CHIP upload/download harness is attached to the Logic Board (LCB) on J1 (upper right
hand corner) and the other end is mounted on the swing panel in a depression just above the
display. Six of these harnesses included in this package.

Using A Volt-Ohm Meter
Before you use your meter for the first time, read the instructions that came
with your meter carefully. The instructions in this document are generic
and should not be considered as instructions on how to use your meter. If at
any time while using a meter you are not completely comfortable with what
you are doing, STOP and call a certified electrician.
WARNING: Always turn off power to the circuit you are about to measure before you probe
the test leads into high-voltage points.
CAUTION: Be sure to select the correct function before you touch the test leads to the circuit
or component to be tested.
1. Press ON/OFF to turn on the meter if it is not already on.
2. Turn the selector to change between the meter's functions and familiarize yourself with the
displays.
Note: The display might show a phantom reading in some DC and AC voltage ranges when the
test leads are not connected to a circuit. This is normal. The high input sensitivity produces a
"wandering" effect. When you connect the test leads to a circuit, a real measurement appears.
Measuring High-Voltage Circuits
When you use the meter to check a high-voltage circuit, do not try to position both test leads at
once. Instead, use an insulated slip-on alligator clip to clamp one of the test leads to the neutral
or ground lead of the circuit (usually a bare, green, or white lead in AC wiring circuits). Then
probe for voltages using the other test lead. This helps prevent accidentally touching a hot wire,
because you need to concentrate on only one test lead.
Using Display Hold (not found on all meters)
Your meter's display hold feature lets you hold the current reading on the
meter's display. The meter holds the measured value on the display even if you remove the test
leads from the circuit.
Using Range Hold
Your meter is preset to automatically set a constant measurement range for
voltage or resistance you measure. The range hold feature lets you hold the current measurement
range.
Making Measurements
Measuring DC/AC Voltage
WARNING: Never clamp a test lead to a hot wire (usually red, black, or
blue in AC wiring circuits). If one lead is clamped to a hot
wire and you touch the meter's other probe, you could receive
an electric shock.
The maximum input limit for voltage measurement is 1000V DC or 750 V AC (RMS). To avoid
electrical shock and damage to the meter, never try to measure a DC voltage above 1000 volts or
an AC voltage above 750 volts RMS.
Follow these steps to measure AC or DC voltage.
1. Press ON/OFF to turn on the meter if it is not already on.
2. Set the selector to ( V ) to measure DC voltages or ( v ) to measure AC voltages.
3. Touch the test leads to the circuit you want to test.
When you measure AC voltages, AC appears on the left side of the display and V or mV appear
on the right side.
When you measure DC voltages, only v or mv appears on the right side of the display.
Note: If the polarity of the voltage you are testing is negative, a thick, black bar, appears on the
left slide of the display (on some meters).
Measuring Three-Phase AC Voltage
Because of the dangers inherent in measuring three-phase circuits, we
very strongly recommend you do not use a meter for such applications.
Measuring Resistance
The resistance measuring circuit in your meter compares the voltage gained through a known
resistance (internal) with the voltage developed across an unknown resistance.
WARNING: Be sure the circuit under test has all power removed and
any associated capacitors are fully discharged before you make a
resistance measurement
Follow these steps to measure resistance.
1. Remove all power from the circuit under test and discharge all capacitors.
2. Set the selector to Ohms (  )
CAUTION: Never connect the test leads to a source of voltage while the selector is set to
OHM (  )
3. Touch the test leads across the circuit you want to measure, or remove one of the leads of the
component you want to measure from its circuit and touch the test leads across the component.
The resistance value appears.
Note: With no resistance connected across the test leads (meaning resistance is infinite), O.L
appears when you set the meter to measure resistance. This is normal.
If you are measuring resistance of about 1 MOhm or more, the display might take a few seconds
to stabilize. This is normal.
As with the voltage range, use the measuring units that appear on the display to determine
the current resistance range. If only Ohms appears, the values of the measurements are in Ohms.
If K and Ohms appear, the meter is measuring kiliOhms (1 kilOhm = 1000 Ohms). If M and
Ohms appear, the meter is measuring MegOhms (1 MegOhm = 1,000,000 Ohms).
Checking Continuity
You can use the meter to check for shorted or open electrical circuits.
1. Remove all power from the circuit under test and discharge all capacitors.
2. Set the selector to Ohms (  )
CAUTION: Never connect the test leads to a source of voltage while the
selector is set to Ohms (  )
3. If you have not already done so, plug the black test lead's end into COM and the red test lead's
end into the V/Ohm jack.
4. Touch the test leads across the circuit you want to measure. The buzzer sounds if the circuit
resistance is less than about 50 Ohms (meaning the circuit is continuous or shorted).
