    3. Function description 3.1 General Functions 3.1.1 DATA HOLD mode Data Hold mode makes the meter stop updating the display. Enabling Data Hold function in autorange mode makes the meter switch to Manual ranging mode, but the full-scale range remains the same.

  • Page 9: Measurement Functions

    To enter and exit the relative measurement mode: 1) With the Meter in the desired function, touch the test leads to the circuit on which you want future measurement to be based. 2) Press REL key to store the measured value and activate the relative measurement mode. The difference between the reference value and subsequent reading is displayed.
  • Page 10 The Meter's resistance ranges are 600.0Ω, 6.000kΩ, 60.00kΩ, 600.0kΩ, 6.000MΩ and 60.00MΩ. To measure resistance: 1) Set the rotary switch to Ω Ω Ω Ω range. 2) Connect the black and red test leads to the COM and VΩ terminals respectively. 3) Connect the test leads to the circuit being measured and read the displayed value.
  • Page 11 3.2.4 Continuity Check To avoid electrical shock and/or damage to the instrument, disconnect circuit power and discharge all high-voltage capacitors before testing for Continuity. To test for continuity: 1) Set the rotary switch to Ω Ω Ω Ω range. 2) Press the SELECT key twice to activate Continuity Check. 3) Connect the black and red test leads to the COM and Ω...
  • Page 12 1) With the meter in the desired function (AC Voltage or AC Current), press the Hz/DUTY key. 2) Read the frequency of the AC signal on the display. 3) To make a duty cycle measurement, press the Hz/DUTY key again. 4) Read the percent of duty cycle on the display..
  • Page 13 The Meter's current ranges are 600.0µA, 6000µA, 60.00mA, 600.0mA, 6.000A and 10.00A. To measure current: 1) Turn off power to the circuit. Discharge all high voltage capacitors. 2) Set the rotary switch to the µA, mA or A range. 3) Press the SELECT key to select DCA or ACA measuring mode. 4) Connect the black test lead to the COM terminal and the red test leads to the mA terminal for a maximum of 600mA.
