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.

CMRR (Common Mode Rejection Ratio) Common mode voltage is voltage present on both the COM and VOLTAGE input terminals of a DMM, with respect to ground. CMRR is the DMM's ability to reject common mode voltage effect that can cause digit rattle or offset in voltage measurements. - 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 Temperature function (AM-130 & AM-150 only) Press SELECT button momentarily to toggle between ° C and ° F readings, and the new setting will be saved automatically in the non-volatile memory as power up default. Note: Be sure to insert the banana plug K-type temperature bead probe with correct polarities.
- 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 Auto leads resistance calibration When entering the 50 range manually by RANGE button for high precision low resistance measurement, this feature will prompt you to short the inputs for calibration. The display shows “Shrt”. Simply short the leads for about 3 seconds until the display shows zero, then the resistance in the leads and in the internal protection circuitry of the meter is compensated automatically.
- Page 11 The instrument equips with an optical isolated interface port at the meter back for data communication. Optional purchase PC interface kit is required to connect the meter to the PC computer (refer to www.amprobe.com). The Data Recording System software equips with a digital meter, an analog meter, a comparator meter, and a Data Graphical...
- Page 12 50ms MAX/MIN at fast 20/s measurement mode (AM-130 only) Press MAX/MIN button momentarily to activate MAX/MIN recording mode. The LCD symbols “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.
- Page 13 Backlighted display Press the SELECT button for 1 second or more to turn on or off the display backlight function. 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 (AM-130 only)
- Page 14 Relative mode (AM-130 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.
- Page 15 Data Logging mode (AM-150 only) Press the Start button for 1 second or more to start “Strt” or to stop “StoP” the data logging mode. Press the SELECT button momentarily to toggle the LCD display to the measuring data or the logged data item number. Press the Start button momentarily to pause or to continue.
- Page 16 To recall, switch on the meter, then press the start, up, or down arrow button momentarily to “CALL” the logged data. The LCD annunciator “C” will be flashing to indicate on screen logged data review. The logged data can also be downloaded to a PC computer through the meter RS232C capability with the additional RSKIT1 PC interface kit.
- Page 17 4) Press the up (or down) arrow button momentarily while press-and-hold the HOLD button to search throughout the turning points (max, min, max, min, …etc) of the logged data. The LCD annunciator “MAX” or “MIN” will be flashing to indicate a downward or upward turning point.
