- Meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for Category III installations up to 1,000V
The BK Precision 390A digital multimeter (also known as a multitester) is an average-sensing, auto-ranging meter for measuring current, voltage, resistance, capacitance, frequency, and temperature in electrical testing applications. The meter comes with a set of detachable test leads. A K-type thermocouple probe is included for taking temperature measurements. An audible continuity sensor confirms a circuit conducts electricity, and a diode test detects proper functioning of a circuit’s diodes. The LCD shows readings in digits and on a 41-segment bar graph. It displays the present measurement or the highest or lowest reading in a session, for tracking sudden changes in readings. The relative mode stores a reading in memory to use as a zero point for subsequent readings so that multiple readings can be compared. The peak maximum or minimum function records instantaneous peak values for current and voltage. The microamp function identifies current changes in flame detector applications. A hold function keeps a reading on the display, even after the meter has been disconnected. An alarm sounds when the test leads are connected to the wrong jack for the measurement being taken. A USB data port connects the meter to a computer (USB cable and software are included). The unit automatically turns off after 30 minutes of nonuse to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced. The meter's body is made of molded rubber, which helps protect it against damage from falls, impacts, and abrasion.
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 an undistorted waveform. When turned on, the meter is in auto-ranging mode and automatically selects the correct operating range for the property being measured. It can be switched to manual-ranging mode,
