The Amprobe AM-240 Autoranging Multimeter with Temperature Sensor has autoranging and manual controls for measuring temperature, current, voltage, capacitance, resistance, duty cycle, and frequency in HVAC and industrial electrical testing applications. The meter measures AC/DC current to 10 amps, AC/DC voltage to 600V, capacitance to 4,000 microfarads, resistance to 40 megaohms, duty cycle from 0.1 to 99.9 percent at frequencies lower than 10 kHz, and frequency to 10 MHz. A K-type thermocouple probe with banana plug measures temperature from -58 to 1,382 degrees F (-50 to 700 degrees C) with a resolution of one degree. The dual-display LCD screen shows current and voltage. Included test leads measure circuit voltage, capacitance, resistance, frequency, and duty cycle, and test for continuity and proper functioning of circuit diodes. The microamps measurement feature has a 0.1 microamp resolution at the 400 microamp range, and a 1 microamp resolution at the 4,000 microamp range for identifying small current changes. The maximum reading mode displays the highest measurement in a session, and an audible continuity buzzer confirms that a circuit is capable of conducting current. The data hold function keeps the desired reading on the display after disconnecting the probe. A relative zero mode stores a reading in memory to use as a zero point for subsequent readings, an auto power-off mode turns off the unit after 30 seconds of non-use to conserve battery life and can be disabled, and a low-battery indicator signals when the meter's batteries need to be replaced. A tilt stand holds the meter at an angle for reading. This average sensing, or average responding, meter provides accurate readings when measuring linear loads where the current or voltage has a sinusoidal waveform, such as standard induction motors and incandescent lights. The meter has a 4,000-count resolution, meaning that it can display up to 4,000 units (3-3/4 digits) before the operating range needs to be changed. It meets International Electrotechnic...
