Safety Information • The 37XR Digital Multimeter is UL, CSA, 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.
Introduction The 37XR is a true rms autoranging handheld digital multimeter for measuring or testing the following: • DC and AC voltage • Capacitance • DC and AC current • Diodes • Resistance • Continuity • Inductance • dBm • Frequency •...
Measuring DC Voltage See Figure 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 E , Black to COM 4. Connect the Test Probes to the circuit test points. 5.
5. Open the test circuit ( X ) to establish measurement points. 6. Connect the Test Probes in series with the load. 7. Turn on power to the circuit being measured. 8. Read the display, and, if necessary, correct any overload ( ) conditions.
Measuring Inductance See Figure -10- 1. Set the Function Switch to mH or H. 2. If RANGE is displayed, press the RANGE button to enable autoranging. 3. Connect the Test Leads: Red to H mA, Black to COM 4. Turn off power to the circuit being measured. 5.
Additional Features Input Test Lead Warning The meter emits a continuous tone when a test lead is placed in the 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).
Beeper Off The beeper is an aural indicator to identify when the DMM is performing a function, making a range change, detecting a limit, and so on. To disable the beeper use the following procedure: 1. Set the Function Switch to OFF. 2.
During the warranty period any defective test tool can be returned to your Meterman Test Tools distributor for an exchange for the same or like product. Please check the “Where to Buy” section on www.metermantesttools.com for a list of distributors near you.
(1) year period. Meterman Test Tools shall not be liable for loss of use of the multimeter or other incidental or consequential damages, expenses, or economical loss or for any claim or claims for such damage, expenses or economical loss.
