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. - Page 4 1) Transformer Clamp Jaw for AC current magnetic field pick up 2) Hand/Finger Barrier to indicate the limits of safe access of the meter during measurement 3) Push-buttons for special functions & features.

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. DC Voltage, AC Voltage, Hz Frequency functions Set slide-switch to Voltage function position(s). Inputs are made through the test leads terminals. - Page 6 Note: The Hz trigger level is determined by the selected function-range from where the Hz function is activated. In ACV function: Activating the Hz function during significant measurements can get the most appropriate trigger level to avoid electrical noises in most cases. Electrical noise may cause unstable Hz reading.
- Page 7 Ω Ω Ω Ω Resistance, and Continuity functions Inputs are made through the test leads terminals. Slide-switch on defaults at Ω. Press SELECT button momentarily to select Continuity function which is convenient for checking wiring connections and operation of switches. A continuous beep tone indicates a complete wire.
- Page 8 CAUTION (Application and removal of the Clamp-on meter) For non-invasive ACA current measurements, press the jaw trigger and clamp the jaws around only one single conductor of a circuit for load current measurement. Make sure the jaws are completely closed, or else it will introduce measurement errors. Enclosing more than one conductor of a circuit will result in differential current (like identifying leakage current) measurement.
- Page 9 Temperature function (Twin Display Models only) Be sure to insert the banana plug type-K temperature bead probe Bkp60 with correct polarities. Slide-switch on defaults at degree C (Celsius). Press SELECT button momentarily to select degree F (Fahrenheit). You can also use a plug adapter Bkb32 (Optional purchase) with banana pins to type-K socket to adapt other type-K standard mini plug temperature probes.

If a flame signal current with inadequate strength or fluctuation beyond 10%, check the following to avoid the risk of unwanted flame relay dropout : 1-1) For gas or oil flames (Minipeeper): Low supply voltage...

Relative zero mode (Single Display Models only) Relative zero mode allows the user to offset the meter consecutive measurements with the displaying reading as the reference value. The display will now show readings relative to the stored reference value. That is, display = reading - stored value. Press button momentarily toggles to relative zero mode. - Page 12 Cleaning and Storage Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for periods of longer than 60 days, remove the batteries and store them separately. Battery replacement The meters use standard 3V IEC-CR2032 coin batteries In Signle Display Models: One battery is used.
