• • • • • • • • Safety Information The 34XR 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. Do not exceed the maximum overload limits per function (see specifications) nor the limits marked on the instrument itself.
Introduction The 34XR is a True rms autoranging handheld digital multimeter for measuring or testing the following: • DC and AC voltage • Temperature • DC and AC current • Capacitance • Resistance • 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.
Measuring AC Voltage (True rms) E See Figures -2- & -3- See Additional Features to find out the advantages of true rms. 1. Set the Function Switch to . 2. If RANGE is displayed, press the RANGE button to enable autoranging. 3. Connect the Test Leads: Red to , Black to COM 4. Connect the Test Probes to the circuit test points 5. Read the display, and, if necessary, correct any overload ( ) conditions.
E Measuring Resistance See Figure -6- Set the Function Switch to Ω . If RANGE is displayed, press the RANGE button to enable autoranging. Connect the Test Leads: Red to , Black to COM 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.
Measuring Frequency 1. 2. 3. 4. See Figure -11- Set the Function Switch to Hz. Connect the Test Leads: Red to Hz, Black to COM Connect the Test Probes to the signal source. Read the display. The Meter will autorange for the best resolution. Measuring Dutycycle 1. 2. 3. 4. See Figure -12- Set the Function Switch to %. Connect the Test Leads: Red to %, Black to COM Connect the Test Probes to the signal source. Read the display. The Meter will autorange for the best resolution.
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.
To access the battery and the mA fuse remove the two screws holding the Battery/Fuse Cover in place, and lift the cover from the meter. To replace the mA fuse, pry it from its clips using a small screwdriver. A spare mA fuse is located between the battery and the mA fuse. mA Fuse: Fast Blow 315mA/1000V, minimum interrupt rating 30 kA (6.3 x 32 mm) (Meterman FP300) To replace the 10 A fuse: 1) Remove the battery. 2) Remove the four rear-case screws. 3) Separate the case. 4) Remove the 10 A fuse cover.
WARRANTY This 34XR Digital Multimeter is warranted against any defects of material or workmanship within a period of three (3) years following the date of purchase of the multimeter by the original purchaser or original user. Any multimeter claimed to be defective during the warranty period should be returned with proof of purchase to an authorized Meterman Test Tools Service Center or to the local Meterman Test Tools dealer or distributor where your multimeter was purchased. See Repair section for details.
