    1) SAFETY This manual contains information and warnings that must be followed for operating the instrument safely and maintaining the instrument in a safe operating condition. If the instrument is used in a manner not specified by the manufacturer, the protection provided by the instrument may be impaired.

  • Page 3: International Electrical Symbols

    WARNING To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. The meter is intended only for indoor use. To avoid electrical shock hazard, observe the proper safety precautions when working with voltages above 60 VDC or 30 VAC rms. These voltage levels pose a potential shock hazard to the user.

    3) PRODUCT DESCRIPTION This user's manual uses only representative model(s) for illustrations. Please refer specification details for function availability to each model. 1) Antenna for Non-Contact EF- Detection 2) Hand/Finger Barrier to indicate the limits of safe access of the meter during measurement Push-buttons special...

    4) OPERATION CAUTION: Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning. , DCV & DC+ACV (Model 189 only) functions Set slide-switch to Voltage function position(s). Inputs are made through the test leads terminals.
  • Page 6 , DCA (Models 186 & 189 only) & DC+ACA (Model 189 only) functions Set the slide-switch to select A function. Input is made through the clamp jaws for non- invasive current measurements. Defaults at ACA Function. Press SELECT button momentarily and release to select the subject functions in sequence. CAUTION (Application and removal of the Clamp-on meter) For non-invasive current measurements, press the jaw trigger and clamp the jaws around conductor(s) of only one single pole of a circuit for load current measurement.
  • Page 7 Temperature function (Models 185, 188 & 189 only) For Model 189, defaults at C (Celsius) readings. Press SELECT button momentarily and release to select F (Fahrenheit) readings. For Models 185 & 188, defaults at ACA readings. Press SELECT button momentarily and release to select C (Celsius) readings.
  • Page 8 The DCA function is designed especially for HVAC/R flame sensor applications. The 0.1A resolution is useful for identifying the minute current changes in flame detector applications. Flame signal current check should indicate steady flame signal of at least 2A for a rectification type, or 1.5A for an ultraviolet type (8A for self checking systems).
  • Page 9 600V is present, the meter displays the voltage value in appropriate DCV or VFD- ACV, whichever larger in peak magnitude. Note: *Range-Lock and Function-Lock Feature: When a measurement reading is being displayed in AutoCheck mode, press the RANGE or SELECT button momentarily 1 time can lock the range or function it was in.
  • Page 10 mode input impedance increases abruptly from initial 2.5kΩ to a few AutoCheck hundred kΩ’s on high voltage hard signals. “LoZ” displays on the LCD to remind the users of being in such low impedance mode. Peak initial load current, while probing 600VAC for example, can be up to 340mA (600V x 1.414 / 2.5kΩ), decreasing abruptly to approx.
  • Page 11 Note 1. Both ACV (LoZ) & VFD ACV (LoZ) function selections are equipped with low pass filter to deal with VFD (Variable Frequency Device) signals. VFD ACV (LoZ) selection, however, further pre-selects the most appropriate voltage-ranges and thus the Hz trigger levels to best cope with most VFD-Voltage and VFD-Frequency applications.
  • Page 12 2. When using Capacitance function, discharge capacitor(s) before making any measurements. Large value capacitors should be discharged through an appropriate resistance load Electric Field EF-Detection In Voltage, Current or Temperature function, press the EF button for one second or more and release to toggle to EF-Detection feature. The meter displays “E.F.” when it is ready.
  • Page 13 earth connections. Probe-Contact EF-Detection: For more precise indication of live wires, such as distinguishing between live and ground connections, use the Red (+) test probe for direct contact measurements. PC computer interface capabilities The instrument equips with an optical isolated interface port at the meter back for data communication.

    Set Beeper Off Press the RANGE button while turning the meter on to temporarily disable the Beeper feature. Turn the slide switch OFF and then back on to resume. Auto-Power-Off (APO) The Auto-Power-Off (APO) mode turns the meter off automatically to extend battery life after approximately 34 minutes of no rotary switch or push button operations.
  • Page 15 some meter ranges might be largely out of specifications. To avoid mis-leading measurements, stop using the meter and send it for re-calibration. Refer to the LIMITED WARRANTY section for obtaining calibration, repairing or warranty service. Cleaning and Storage Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents.
