3) PRODUCT DESCRIPTION Panel Illustration 1) 3-4/5 digits 5000 counts LCD display 2) Push-buttons for special functions & features 3) Selector to turn the Power On or Off and Select a function 4) Input Jack for 10A (20A for 30sec) current function 5) Input Jack for all functions EXCEPT current (A, mA, A) functions... - Page 5 Analog bar-graph The analog bar graph provides a visual indication of measurement like a traditional analog meter needle. It is excellent in detecting faulty contacts, identifying potentiometer clicks, and indicating signal spikes during adjustments. Average sensing RMS calibrated RMS (Root-Mean-Square) is the term used to describe the effective or equivalent DC value of an AC signal.

terminals of a DMM, with respect to ground. CMRR is the DMM's ability to reject common mode voltage effect that can cause digit rolling or offset in voltage measurements. This series has a CMRR specifications of >60dB at DC to 60Hz in ACV function;... - Page 7 Capacitance, Diode test function Default at . Press SELECT button momentarily to select Diode test function. CAUTION Discharge capacitors before making any measurement. Large value capacitors should be discharged through an appropriate resistance load. Normal forward voltage drop (forward biased) for a good silicon diode is between 0.400V to 0.900V.
- Page 8 Note: Be sure to insert the banana plug K-type temperature bead probe Bkp60 with correct polarities. You can also use a plug adapter Bkb32 (Optional purchase) with banana pins to K-type socket to adapt other standard K type mini plug temperature probes.
- Page 9 Resistance, Continuity functions Default at . Press SELECT button momentarily to select Continuity function that is convenient for checking wiring connections and operation of switches. A continuous beep tone indicates a complete wire. CAUTION Using resistance and continuity function in a live circuit will produce false results and may damage the instrument.
- Page 10 enters the lowest 50 range automatically, press the RANGE button momentarily to get the “Shrt” prompt, then wait about 3 more seconds until the display shows zero. Note: The calibration stays until you change ranges, functions, or go back to auto- ranging mode.

The LCD annunciators “MAX MIN” turn on, and the reading update rate will be increased to 20/second. The meter beeps when new maximum or minimum reading is updated. Press the button momentarily to read throughout the Maximum (MAX), Minimum (MIN), and Maximum minus Minimum (MAX-MIN) readings.

The backlight will also be turned off automatically after 30 seconds to extend battery life. Hold The hold function freezes the display for later view. Press the HOLD button momentarily to activate or to exit the hold function Zoom 5x analog pointer (Models...
- Page 13 Relative mode (Models 815s & 817s only) Relative zero allows the user to offset the meter consecutive measurements with the displaying reading as the reference value. Practically all displaying readings can be set as relative reference value including MAX/MIN feature readings. Press the button momentarily to activate and to exit relative zero mode.

Auto Power Off (APO) The Auto Power Off (APO) mode turns the meter off automatically to extend battery life after approximately 17 minutes of no activities. Activities are specified as: 1) Rotary switch or push button operations, and 2) Significant measuring readings of above 10% of range or non-OL ... - Page 15 If the instrument voltage-resistance input terminal has subjected to high voltage transient (caused by lightning or switching surge to the system) by accident or abnormal conditions of operation, the series fusible resistors will be blown off (become high impedance) like fuses to protect the user and the instrument. Most measuring functions through this terminal will then be open circuit.
