Page 4: Safety Information
Safety Information • The 38XR Digital Multimeter is UL, CSA, and EN61010-1 certified for Installation Category III – 1000V and Category IV – 600V. It is recommended for use with fixed equipment installations, such as, distribution panels, feeders and short branch circuits and lighting systems in large buildings; and for the primary supply level, such as, an electric meter or an overhead or underground utility service. -
Page 5: Introduction
Range Selection In addition to autoranging the 38XR 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 and the range is locked. When appropriate, each subsequent press of the range button steps the meter to the next higher range. -

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 , Black to COM 4. Connect the Test Probes to the circuit test points. 5. -
Page 7: Measuring Ac Or Ac+Dc Current (True Rms)
Measuring DC Current See Figure 1. Set the Function Switch to a current function, µA, mA, or 10A. 2. If AC or AC+DC is displayed, press the yellow button to turn on DC. 3. If the µA function is selected and RANGE is displayed, press the RANGE button to enable autoranging. -
Page 8: Testing For Continuity
Match the polarity of the adapter to the polarity of the thermocouple. 3. Connect the TEMP adapter to the and COM inputs. Note: The 38XR 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. -
Page 9: Measuring Frequency
Measuring dBm See Figure -13- The 38XR measures dBm relative to 1 mW referenced to 50 Ω. That is, 10 dBm = 10 mW, 0 dBm = 1 mW, -10 dBm = 0.1 mW, etc. 1. Set the Function Switch to 2. -
Page 10: True-Rms Measurements
• Pulsed Signals • Any non-sinusoidal ac waveform The 38XR displays the dc, ac, or ac+dc components of a voltage or current measurment. The dc component is the shift level or baseline. The ac component is the area under the waveshape. The ac+dc component is the combined effect of the ac and dc components. -
Page 11: Beeper Off
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. -
