AM-140-A Terminals (to COM) measurement category: V : Category III 1000 Volts AC & DC, and Category IV 600 Volts AC & DC. - Page 7 Per IEC61010-1 2nd Ed. (2001) Measurement Category Measurement Category IV (CAT IV) is for measurements performed at the source of the low-voltage installation. Examples are electricity meters and measurements on primary overcurrent protection devices and ripple control units. Measurement Category III (CAT III) is for measurements performed in the building installation.

Electromagnetic compatibility directive 2004/108/EC UNPACKING AND INSPECTION Your shipping carton should include: 1 AM-140-A or AM-160-A Meter 1 Test Leads (Black x 1; Red x 1) 1 K Type thermal couple with banana plug (For AM-160-A only) 1 Users Manual 1 Single Alkaline 9V battery;... - Page 9 AC True RMS AC True RMS, normally refers as True RMS, identifies a DMM function that is AC coupled, and responds accurately only to the effective RMS AC component value regardless of the waveforms. However, DC component plays an important role in the distorted non-symmetrical waveforms, and will also be of interest sometimes.

measurements. This series has a CMRR specifications of > 80dB at DC to 60Hz in ACV function; and > 120dB at DC, 50 and 60Hz in DCV function. If neither NMRR nor CMRR specification is specified, a DMM’s performance will be uncertain. Analog bar-graph The analog bar graph provides a visual indication of measurement like a traditional analog meter needle. - Page 11 1.800.561.8187 information@itm.com www. .com...

Page 12: Hz Logic Level Frequency And % Duty Cycle Functions
Note: Line Level Frequency measuring function input sensitivity varies automatically with voltage (or current) function range selected. The lower the measuring range the higher the sensitivity. That is, mV function has the highest and the 1000V range has the lowest as in voltage function ranges. It is recommended to first measure the signal voltage (or current) level then activate the Hz function in that voltage (or current) range to automatically get the most appropriate trigger level. -
Page 13: T1-T2 Dual Channels Temperature Function (Am-160-A Only)
Note: Unlike the Line Level Frequency measuring function as previously stated, this Logic Level Frequency function is set only at the highest input sensitivity for measuring digital type electronic signals. T1-T2 Dual Channels Temperature function (AM-160-A 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. -

Resistance, Continuity functions Press SELECT button momentarily to toggle between and Continuity functions. The new setting will be saved automatically to the non-volatile memory as power up default. Continuity function is convenient for checking wiring connections and operation of switches. A continuous beep tone indicates a complete wire. -

Note: Normal forward voltage drop (forward biased) for a good silicon diode is between 0.400V to 0.900V. A reading higher than that indicates a leaky diode (defective). A zero reading indicates a shorted diode (defective). An OL indicates an open diode (defective). Reverse the test leads connections (reverse biased) across the diode. -

�Warning When measuring a 3-phase system, special attention should be taken to the phase-to-phase voltage that is significantly higher than the phase- to-earth voltage. To avoid exceeding the voltage rating of the protection fuse(s) accidentally, always consider the phase-to-phase voltage as the working voltage for the protection fuse(s). -
Page 17: Max/Min Recording Mode
MAX/MIN RECORDING mode Press REC button momentarily to activate MAX/MIN recording mode. The LCD annunciators “R” and “MAX MIN” turn on. 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. -
