DMM with Temperature and Capacitance
The Amprobe 33XR-A digital multimeter with included temperature probe is an average-sensing, manual-ranging meter for measuring current, voltage, resistance, capacitance, and frequency in electrical testing and maintenance applications. The meter comes with a set of detachable test leads and two alligator clips for measuring measure alternating current (AC) and direct current (DC) to 10 amp, AC voltage to 750 volts (V), DC voltage to 1,000V, resistance to 4 megaohms, capacitance to 4,000 microfarads, and frequency to 1 megahertz (MHz). The meter comes with a K-type thermocouple probe and adaptor plug for measuring temperature. The peak + or - function records peak positive or negative values for AC current and AC voltage. The 4,000 microfarad capacitance rating is for testing run/start capacitors on motors. The maximum or minimum reading mode displays the highest or lowest reading in a session to track a sudden increase or decrease in readings. A relative zero mode stores a reading in memory to use as a zero point for subsequent readings, allowing for quick comparison of readings. An audible continuity sensor confirms that the circuit conducts electricity, and a diode test detects whether the circuit's diodes work properly. The hold function keeps a reading on the display, even after the meter is disconnected. An auto power-off mode turns off the unit after 30 minutes of non-use to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced.
This average sensing, or average responding, meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has a sinusoidal waveform. It is a manual-ranging meter and requires that the operator choose the appropriate operating range. The meter has a 4,000-count resolution, meaning it can display up to 3,999 units (3-3/4 digits) before the operating range needs to be changed. It meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for category II installations up to 1,000V (which covers large household appliances and devices connected to a fixed power supply, such as refrigerators and air conditioners), and category III installations up to 600V (which covers items used with enclosed building circuit installations, such as service panel parts, branch circuits, and fixed installations that are connected directly to a building's AC power supply). The meter comes with a magnetic strap that can be used to hang the meter on metal doors or fixtures.
