Making Measurements
Verify Instrument Operation
Before attempting to make a measurement, verify that the instrument is operational
and the battery is good. If the instrument is not operational, have it repaired before
attempting to make a measurement.
Range Selection
In addition to autoranging (Models 15XP-A and 35XP-A only) you can manually
select and lock a range by pressing the RANGE button. RANGE appears on the
display to indicate that manual ranging is active and the range is locked. When
appropriate, each subsequent press of the range button steps the meter to the next
higher range. When the highest range is reached the next press returns the meter
to the lowest range. To return to autoranging press the RANGE button. If RANGE
still shows on the display, autoranging is not available for the selected function.
Use autorange for all initial measurements. Then, when appropriate, use the RANGE
button to select and lock a range.
XWWarning
To avoid electrical shock while manual ranging, use the display
annunciators to identify the actual range selected.
Correcting an Overload (0o or -0o) Indication W
An 0o or -0o indication may appear on the display to indicate that an overload
condition exists. For voltage and current measurements, an overload should be
immediately corrected by selecting a higher range. If the highest range setting does
not eliminate the overload, interrupt the measurement until the problem is identified
and eliminated. The 0o indication is normal for some functions; for example,
resistance, continuity, and diode test.
Measuring DC Voltage See Figure -1-
1. Set the Function Switch to v.
2. Select the desired RANGE. The default DC voltage range is 2 V on the 15XP-A
and 4 V on the 35XP-A.
3. Connect the test leads: Red to E, Black to COM.
4. Connect the test probes to the circuit test points.
5. Read the display, and, if necessary, correct any overload (0o) conditions.

4
Measuring AC Voltage See Figure -2-
1. Set the Function Switch to V.
2. Select the desired RANGE. The default AC voltage range is 2 V on the 15XP-A
and 4 V on the 35XP-A.
3. Connect the test leads: Red to E, Black to COM.
4. Connect the test probes to the circuit test points.
5. Read the display, and, if necessary, correct any overload (0o) conditions.
Preparing for Current Measurements
•Turn off circuit power before connecting the test probes.
•Allow the meter to cool between measurements, if current measurements
approach or exceeds 2 amps.
•A warning tone sounds if you connect a test lead to a current input while a
current function is not selected.
•Open circuit voltage at the measurement point must not exceed 1000 V.
•Always measure current in series with the load. Never measure current across a
voltage source.
Measuring DC Current See Figure -3-
1. Set the Function Switch to a current function, µA, mA, or A.
2. Select the desired RANGE (5XP-A only).
3. Connect the test leads: Red to mA or A, Black to COM.
4. Turn off power to the circuit being measured.
5. Open the test circuit (X) to establish measurement points.
6. Connect the test probes in series with the load (to the measurement points).
7. Turn on power to the circuit being measured.
8. Read the display, and, if necessary, correct any overload (0o or -0o) conditions.
Measuring AC Current See Figure -4-
1. Set the Function Switch to a current function and range, µA, mA, or A.
2. Select the desired RANGE (5XP-A only).
3. Connect the test leads: Red to mA or A, Black to COM.
4. Turn off power to the circuit being measured.
5. Open the test circuit (X) to establish measurement points.
6. Connect the test probes in series with the load (to the measurement points).
7. Turn on power to the circuit being measured.
8. Read the display, and, if necessary, correct any overload (0o) conditions.

5
Measuring Resistance See Figure -5-
1. Set the Function Switch to Ω.
2. Select the desired RANGE (5XP-A, 15XP-A).
3. Connect the test leads: Red to E, Black to COM.
4. Turn off power to the circuit being measured. Never measure resistance across
a voltage source or on a powered circuit.
5. Discharge any capacitors that may influence the reading.
6. Connect the test probes across the resistance.
7. Read the display. If 0o appears on the highest range, the resistance is too large
to be measured or the circuit is an open circuit.
8. (15XP-A) The 2000 MΩ range has a fixed 10-count offset in the reading. For
example, when measuring 1100 MΩ, the display reads 1110. The 10 residual
must be subtracted to obtain the actual value of 1100 MΩ
Testing for Continuity See Figure -6-
1. Set the Function Switch to R.
2. Connect the test leads: Red to E, Black to COM.
3. Turn off power to the circuit being measured.
4. Discharge any capacitors that may influence the reading.
5. Connect the test probes across the resistance or the two points of test.
6. Listen for the tone that indicates continuity (< 40 Ω).
Testing Diodes See Figure -7-
1. Set the Function Switch to G.
2. Connect the test leads: Red to E, Black to COM.
3. Turn off power to the circuit being measured.
4. Free at least one end of the diode from the circuit.
5. Connect the test probes across the diode.
6. Read the display. A good diode has a forward voltage drop of about 0.6 V. An
open or reverse biased diode will read 0o.
Measuring Capacitance (35XP-A only) See Figure -8-
1. Set the Function Switch to the P function.
2. Connect the test leads: Red to h, Black to COM.
4. Turn off power to the circuit being measured.
5. Discharge the capacitor using a 100 kΩresistor.
6. Free at least one end of the capacitor from the circuit.
7. Connect the test probes across the capacitor.
8. Read the display.

6
Measuring Temperature (35XP-A only) See Figure -9-
1. Set the function switch to appropriate °C or °F range.
2. Connect the K-type thermocouple to a TEMP adapter (XR-TA).
Match the polarity of the adapter to the polarity of the thermocouple.
3. Connect the TEMP adapter to the E and COM inputs.
Note: The 35XP-A is compatible with all K-type thermocouples. The K-type bead
thermocouple supplied with the meter is not intended for contact with liquids or electrical
circuits.
4. Expose the thermocouple to the temperature to be measured.
5. Read the display.
Measuring Frequency (35XP-A only) See Figure -10-
1. Set the Function Switch to Hz.
2. Connect the test leads: Red to Hz, Black to COM.
3. Connect the test probes to the signal source.
4. Read the display.

1. Range switch may be set to OFF or any function/range.
2. Test leads are not used for the NCV test.
3. Press the NCV button. The display goes blank, a tone sounds and the red LED
next to the NCV button on the front panel lights up to verify that the instrument
is operational. While pressing the button, hold the top-center of the meter z
(sensor location) close to the conductor/circuit in question.
4. If a voltage in the range of 70 to 600 V ac is present, a tone sounds and the red
LED next to the NCV button on the front panel lights up.
Testing Battery Voltage (5XP-A only) See Figure -12-
1. Set the Function Switch to the appropriate BATT setting, 1.5 V or 9 V.
2. Connect the test leads: Red to BATT 1.5 V or BATT 9 V, Black to COM.
3. Connect the test probes across the battery. The meter applies an appropriate
load to the battery.
4. Read the display. A good 1.5 volt battery should measure >1.2 V, and a good
9 volt battery should measure > 7.2 V.

7
Testing Logic Levels (15XP-A only) See Figure -13-
The 15XP-A tests logic levels for TTL logic. The meter displays 0o plus a ∧for a
high-level (true) condition. The meter beeps and displays an 0o and a ∨for a
low-level (false) condition. See Specifications for the logic 1 and logic 0 voltage
limits. Out-of-limits indications are displayed as 0o only, no ∧,∨ or beep occur.

Additional Features
Input Test Lead Warning
The meter emits a continuous tone when a test lead is placed in the mA or Ainput
jack and the Function/Range Switch is not set to a correct current position. (If the
meter is connected to a voltage source with leads connected for current, very high
current could result). All current ranges are protected by fast acting fuses.
MIN MAX Measurements (Model 5XP-A only)
The MIN MAX feature reads and updates the display to show the maximum or
minimum value measured after you press the MIN MAX button.
Pressing the MIN MAX button for less than 1 second will put the meter into a mode
of displaying the maximum or minimum readings. Each time the button is pressed,
the meter will cycle to the next display mode. Press the MIN MAX button for more
than 1 second to disable this feature.
Auto Power Off (Models 15XP-A and 35XP-A only)
Auto Power Off is a battery saving feature that puts the meter into a sleep mode if
the Function/Range Switch has not changed position in the last 10 minutes. To
wake the meter turn the Function/Range Switch to another position.
The Auto Power Off feature can be disabled to keep the meter from going to sleep.
To disable the Auto Power Off feature use the following procedure:
1. Set the Function Switch to OFF.
2. Press and hold the Range button while turning the Function Switch from OFF
to the desired function.
3. Release the Range button. The Auto Power Off feature will remain disabled until
the meter is turned off and then on.
HOLD Measurements
The HOLD button causes the meter to capture and continuously display a
measurement reading. To use the HOLD feature make a measurement, and then,
after the reading has stabilized, momentarily press the HOLD button. You can
remove the test leads and the reading will remain on the display. Pressing the
HOLD button again releases the display.
