    Before operating the device, you must read, understand, and follow all in- structions, dangers, warnings, cautions, and notes. Note Flir Systems reserves the right to discontinue models, parts or accessories, and other items, or to change specifications at any time without prior notice. Note Remove the batteries if the device is not used for an extended period of time.
  • Page 9 2 Safety information WARNING Do not measure the current on a circuit when the voltage increases to more than 600 V. This can cause damage to the instrument and can cause injury to persons. WARNING You must disconnect the test leads from the circuit that you did a test on be- fore you change the range.
  • Page 10 2 Safety information WARNING Do not use the device as a tool to identify live terminals. You must use the cor- rect tools. Injury to persons can occur if you do not use the correct tools. WARNING Make sure that children cannot touch the device. The device contains danger- ous objects and small parts that children can swallow.

    4 Description Figure 4.2 Rear view Probe clips. Tilt stand. Work light. Battery compartment cover. 4.2 Function switch The meter can measure voltage through the probe inputs. A low- impedance load is placed across the inputs to stabilize the measurement. The meter is in full power-saving mode.

  • Page 15: Function Buttons

    4 Description The meter can measure resistance, continuity, or diode polarity through the probe inputs. The type of measurement is selected by button. The meter can measure capacitance through the probe inputs or temperature through a thermocouple adapter. The type of meas- urement is selected by the button.

  • Page 16: Display Description

    4 Description • Press the button to enable/disable the display backlight. • Press and hold the button for 2 seconds to enable/disable the work light. Press the button to enable/disable MeterLink (Bluetooth) commu- nication, see section 5.14 Streaming measurement data using Bluetooth, page 22.

  • Page 19: Operation

    5 Operation Note Before operating the device, you must read, understand, and follow all in- structions, dangers, warnings, cautions, and notes. Note When the meter is not in use, the function switch should be set to the position. Note When connecting the probe leads to the device under test, connect the nega- tive lead before connecting the positive lead.

  • Page 20: Auto/Manual Range Mode

    5 Operation • If the function switch is set to the position, the meter attempts to deter- mine if the device under test is a resistor, capacitor, or diode. Auto select mode is the default mode of operation. When a new function is se- lected with the function switch, the starting mode is Auto select and the indi- cator is displayed.

  • Page 21: Resistance Measurements

    5 Operation For stabilized voltage measurements, place a low-impedance load across the probe inputs. Connect the probe leads in parallel to the part under test. Read the voltage value on the display. 5.5 Resistance measurements WARNING Do not do diode, resistance or continuity tests before you have removed the power from the capacitors and from a device during a test.

  • Page 22: Diode Test

    5 Operation If the resistance is 25 ± 5 Ω (nominal) or less, the meter beeps. 5.7 Diode test WARNING Do not do diode, resistance or continuity tests before you have removed the power from the capacitors and from a device during a test. Injury to persons can occur.

  • Page 23: Type K Temperature Measurements

    5 Operation Insert the black probe lead into the negative terminal and the red probe lead into the positive terminal. Touch the tips of the probe across the part under test. Read the capacitance value on the display. Note For very large capacitance values, it may take several minutes for the measurement to settle and the final reading to stabilize.

  • Page 24: Extended Functionality

    5 Operation Set the function switch to the position. Insert the black probe lead into the negative terminal and the red probe lead into one of the following positive terminals: • for high current measurements. • for low current measurements. Use the button to select AC, DC, or AC+DC voltage measurement.
  • Page 25 5 Operation 5.11.2 LPF mode (ACV only) In LPF mode, high-frequency noise is eliminated from the voltage measurement by a low-pass filter (LPF). LPF mode is available when measuring AC voltage. Use the selector pad to select and enable LPF mode. 5.11.3 Peak mode (ACV and ACA only) In Peak mode, the meter captures and displays the positive and negative peak values, and updates only when a higher/lower value is registered.
  • Page 26 5 Operation 5.11.6 Relative mode In Relative mode, the difference (Δ) between the current reading and a stored reference value is displayed in the main display. The reference value is displayed in the secondary display. Use the selector pad to select and enable Relative mode.
  • Page 27 5 Operation 5.11.9 Sampling mode In Sampling mode, the meter logs measurement data at the user-programmed sampling rate. The logged data can be recalled at a later time for review. Up to 20 000 records can be logged into memory. The sampling rate can be set to a value in the range 0.5 to 600 seconds.

    5.14 Streaming measurement data using Bluetooth 5.14.1 General Some IR cameras from Flir Systems support Bluetooth communication, and to those cameras you can stream measurement data from the meter. The data is then merged into the result table in the IR image.
  • Page 29 5 Operation Streaming measurement data is a convenient way to add important information to an IR image. For example, when identifying an overheated cable connection, you may want to know the current in that cable. 5.14.2 Procedure Pair the IR camera with the instrument. Refer to the camera manual for infor- mation on how to pair Bluetooth devices.
