Digital Multimeter HP-770HC
HP-770HC:measure DC & AC voltage, DC & AC current ( 600A range with AC/DC current clamp adapter), resistance, capacitor, frequency, duty cycle, temperature, transistor hFE, Non Contact AC Voltage (NCV) detection, positive diode voltage fall and audible co file(774688KB)
- NON-CONTACT VOLTAGE TEST (NCV): When the voltage test is greater than 90 V (RMS), near the conductor, the instrument sensor will emit light and buzz.
- AUTO RANGING & AUTO POWER OFF: DC and AC current (600A range with AC/DC current clamp adapter), resistance, capacitance, frequency, duty cycle, temperature, transistor hFE.
- LOAD TIME LIMIT & CONTINUITY TEST: Use PTC protection circuit to measure resistance, temperature and frequency. If the measured resistance is less than 100Ω, buzzer will sound
- LOW POWER INDICATOR & LCD DISPLAY: 3 1/2 digit LCD, which can be displayed in areas with insufficient light. Use a battery indicator so you don't accidentally run out of juice.
- WIDE ELECTRICAL MEASUREMENT RANGE: Accurately meet AC/DC spanning; AC/DC current; Resistance, Capacitor, Frequency and Temperature. Designed to safely and accurately troubleshoot a variety of automotive and household electrical.
