Safety Information

• The 34XR-A Digital Multimeter is UL, cUL, and EN61010-1 certified for Installation Category III - 600V and Category II - 1000V. It is recommended for use with local level power distribution, appliances, portable equipment, etc, where only smaller transient overvoltages may occur, and not for primary supply lines, overhead lines and cable systems.
  CAT II: Is for measurements performed on circuits directly connected to the lowvoltage installation.
  CAT III: Is for measurements performed in the building installation.
• Do not exceed the maximum overload limits per function (see specifications) nor the limits marked on the instrument itself. Never apply more than 1000V dc/750 V ac rms between the test lead and earth ground.
• Inspect the 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 test probe tips.
• Do not operate the instrument in an explosive atmosphere.
• Exercise extreme caution when: measuring voltage >20V // current >10mA // AC power line with inductive loads // AC power line during electrical terms // current, when the fuse blows in a circuit with open circuit voltage >1000V // 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.
• Remove test leads before opening the Battery Cover or case.

The 34XR-A is a True rms autoranging handheld digital multimeter for measuring or testing the following:

• DC and AC voltage - Temperature - Resistance
• DC and AC current
• Capacitance
• Diodes
• Frequency - Continuity - Dutycycle

Additional features include: MIN MAX, HOLD, Backlight, and Range Lock

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 the 34XR-A allows you to manually select and lock a range by pressing the RANGE button. RANGE appears on the display to indicate that manual ranging is active. 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 and hold the RANGE button for 2 seconds. RANGE no longer shows on the display. Use autorange for all initial measurements. Then, when appropriate, use the RANGE button to select and lock a range.

Warning: To avoid electrical shock while manual ranging use the display annunciators to identify the actual range selected.

Correcting an Overload (OL or -OL) Indication

An OL 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 OL indication is normal for some functions; for example, resistance, continuity, and diode test.

ADDITIONAL FEATURES

Input Test Lead Warning

The meter emits a continuous tone when a test lead is placed in the A mA or 10A input 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.

True-rms Measurements

For ac measurements most DMMs average the ac input signal and display the result as an estimated rms value. This average-responding method is accurate for sinusoidal waveforms, but can be very inaccurate for distorted waveforms. To ensure the most accurate measurements, always use a true-rms DMM when measuring ac voltage or ac current on circuits for the following kinds of applications:

• Power Supplies - diodes - Controllers
• Power Limiting - SCR or Triac - Starting - motors
• Florescent Lighting
• ballasts
• Speed Control
• motors
• Any non-sinusoidal ac waveform - Pulsed Signals

MIN MAX Measurements

The MIN MAX function 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, minimum, or actual readings. Each time the button is pressed, the meter will cycle to the next display mode as shown in the table below. Press the MIN MAX button for more than 2 seconds to exit MIN MAX.

Button Display Value Displayed
< 1 second M	AX Maximum	value after feature activated
< 1 second M	N Minimum	value after feature activated
< 1 second M	N MAX (blinks)	Normal measurement, actual reading
>2 seconds Exit MIN MAX		Normal measurement, actual reading

Auto Power Off

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 30 minutes. To wake the meter turn it off and then on.

The Auto Power Off feature can be disabled to keep the meter from going to sleep. This feature is useful when using the MIN MAX mode for extended periods. To disable the Auto Power Off feature use the following procedure:

1. Set the Function Switch to OFF.
2. Press and hold the MIN MAX button while turning the Function Switch to the desired function.
3. Continue to press the MIN MAX button until the display finishes this initialization period and the reading settles.
4. Release the MIN MAX 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.

Backlight

Pressing the button illuminates the display with a blue backlight.

The backlight will automatically turn off in about 60 seconds.

Frequent use of the backlight will decrease battery life.

PRODUCT MAINTENANCE

Cleaning

To clean the meter, use a soft cloth moistened with water. To avoid damage to the plastic components do not use benzene, alcohol, acetone, ether, paint thinner, lacquer thinner, ketone or other solvents to clean the meter.

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 + appears 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.
