XWSafety Information
To Avoid possible electric shock, personal injury, damage to the meter or the
equipment under test, adhere to the following practices:
•Do not exceed the maximum overload limits per function (see specifications)
nor the limits marked on the instrument itself. Never apply more than 600 VDC
between the test lead and earth ground.
•Inspect DMM, test leads and accessories before every use. Do not use any
damaged part.
•Never ground yourself when taking measurements. Do not touch exposed
circuit elements or probe tips.
•Do not operate the instrument in an explosive atmosphere.
•Exercise extreme caution when measuring voltage >20 V // current >10 mA //
AC power line with inductive loads // AC power line during electrical storms //
current, when the fuse blows in a circuit with open circuit voltage >600 V //
servicing CRT equipment.
•Always measure current in series with the load – NEVER ACROSS a voltage
source. Check fuse first. Never replace a fuse with one of a different rating.
•Do not change the position of the Function/Range Switch while the MIN MAX or
the HOLD feature is enabled. Erroneous readings will result.
•Remove test leads before opening battery or case to change battery or fuses.

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
you attempting to make a measurement.
Correcting an Overload (0o) Indication W
An oor 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 oindication is normal for some functions; for example,
resistance, continuity, and diode test.
Measuring DC Voltage See Figure -1-
1. Set the Range Switch to an appropriate L range.
Select the highest range and work down if the voltage level is unknown.
2. Connect the Test Leads: Red to VΩG, Black to COM.
3. Connect the Test Probes to the circuit test points.
4. Read the display, and, if necessary, fix any overload (o) conditions.
Measuring AC Voltage See Figure -2-
1. Set the Range Switch to an appropriate K range.
Select the highest range and work down if the voltage level is unknown.
2. Connect the Test Leads: Red to VΩG, Black to COM.
3. Connect the Test Probes to the circuit test points.
4. Read the display, and, if necessary, fix any overload (o) 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 10 amps.
•A warning tone sounds if you connect a test lead to a current input before you
select a current range.
•Open circuit voltage at the measurement point must not exceed 600 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 Range Switch to an appropriate Arange.
Select the highest range and work down if the current level is unknown.
2. Connect the Test Leads: Red to mA or 10 A, Black to COM.
3. Turn off power to the circuit being measured.
4. Open the test circuit (X) to establish measurements points.
5. Connect the Test Probes in series with the load.
6. Turn on power to the circuit being measured.
7. Read the display, and, if necessary, fix any overload (o) conditions.
Measuring AC Current See Figure -4-
1. Set the Range Switch to an appropriate ? range.
Select the highest range and work down if the current level is unknown.
2. Connect the Test Leads: Red to mA or 10 A, Black to COM
3. Turn off power to the circuit being measured.
4. Open the test circuit (X) to establish measurements points.
5. Connect the Test Probes in series with the load.
6. Turn on power to the circuit being measured.
7. Read the display, and, if necessary, fix any overload (o) conditions.
Measuring Resistance See Figure -5-
1. Set the Range Switch to an appropriate Ωrange.
Select the highest range and work down if the resistance level is unknown.
2. Connect the Test Leads: Red to VΩG, Black to COM.
3. Turn off power to the circuit being measured. Never measure resistance across
a voltage source or on a powered circuit.
4. Discharge any capacitors that may influence the reading.
5. Connect the Test Probes across the resistance.
6. Read the display. If oappears on the highest range, the resistance is too large
to be measured.
Measuring Continuity (<50 Ohms) See Figure -6-
1. Set the Range Switch to R.
2. Connect the Test Leads: Red to VΩG, 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.
6. Listen for the tone that indicates continuity (< 50 Ohms).
Checking Diodes See Figure -7-
1. Set the Range Switch to G.
2. Connect the Test Leads: Red to VΩG, 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 o.

Measuring NCV (Non-Contact Voltage) See Figure -8-
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
(sensor location) close to the conductor/circuit in question.
4. If a voltage of 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 (1.5 and 9 volt) See Figure -9-
1. Set the Range 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.
Additional Features
Input Lead Warning
The 30XR-A emits a continuous tone to indicate that the user has placed the unit in
a potentially dangerous configuration. Specifically, a test lead is in a current
connector and the Range Switch is set to measure some other function. If, in this
configuration, the DMM is connected to a voltage source, very high and potentially
dangerous current could result. The meter includes fast acting fuses as additional
protection for all current ranges.
MIN MAX Measurements
XWWARNING
To avoid erronoeus readings, do not change the position of the
Function/Range Switch while the MIN MAX function is enabled.
The MIN MAX function works within the active measurement mode to capture and
display the minimum or maximum reading associated with that measurement.
Pressing the MIN MAX button for less than 1 second enables the function and
shows MIN or MAX along with the appropriate minimum or maximum reading on
the display. Each subsequent press toggles between the two modes. To exit the
function, press the MIN MAX button for more than 1 second.
HOLD Measurements XWWARNING
To avoid erronoeus readings, do not change the position of the
Function/Range Switch while the HOLD function is enabled.
The HOLD function is used to make a measurement and hold the reading after
removing the leads from the test circuit. Pressing the HOLD button during a
measurement will capture and hold the reading. Pressing the HOLD button again
will release the display for subsequent measurements.

Product Maintenance
Cleaning
To clean the meter, use a soft cloth moistened with water. Using benzene, alcohol,
acetone, ether, paint thinner, lacquer thinner, ketone or other solvents may deform
or discolor the meter and its display.
Troubleshooting
If the meter appears to operate improperly, check the following items first.
1. Review the operating instructions to ensure the meter is being used properly.
2. Inspect and test the continuity of the test leads.
3. Make sure the battery is in good condition. The low battery symbol Bappears
when the battery falls below the level where accuracy is guaranteed. Replace a
low-battery immediately.
4. Check the condition of the fuses if the current ranges operate incorrectly.
XWWARNING
To avoid electrical shock remove the test leads from both the
meter and the test circuit before accessing the battery or the
fuses.
Battery and Fuse Replacement See Figure -10-
