The TPI 270 digital clamp meter is an average-sensing, manual- and auto-ranging multimeter for measuring current, voltage, resistance, capacitance, and frequency in electrical testing applications. It has a clamp that measures AC current to 400 amperes). The clamp has two jaws that can close around an electrical conductor up to 35mm (1.37") in diameter to measure current without touching or interrupting the circuit. A set of test leads is included for measuring DC current to 400 microamperes, AC and DC voltage to 600V, resistance to 40 megohms, voltage frequency to 400mHz (megahertz), and capacitance to 40,000 microfarads. The meter comes with a K-type thermocouple probe for measuring temperature to 1,000 degrees F. Its relative function allows a measurement to be set as a reference value, and it displays the subsequent measurements as positive or negative deviations from that value. The peak hold function records the maximum measurement of a current surge. The maximum/minimum function records the highest and lowest readings in a session to track a sudden increase or decrease in readings. To aid documentation of readings and capture readings in tight spaces, the data hold function keeps the most recent reading on the display after disconnecting from the circuit. An audible continuity sensor confirms that the circuit conducts electricity, and a diode check detects whether a circuit's diodes are working properly. The meter's inrush current function analyzes the surge current at the startup of motors and other inductive loads to provide accurate, stable measurements. A non-contact voltage detector senses voltage without making contact with the circuit. The meter has a rotary switch to select the property to measure, and a 4,000-count LCD that shows readings numerically and in a 41-segment bar graph. The unit operates on a single 9V battery, and turns off automatically after 30 minutes of non-use to conserve battery life. It has a low-battery indicator that signals when the battery needs to be replaced. Clamp meters ...
