The Chauvin Arnoux CA745N Digital Voltage Tester can be used to measure AC and DC voltages up to 690V. This instrument contains seven voltage thresholds and is able to automatically ascertain as to whether the voltage is AC or DC.
In addition to testing, measuring and identifying voltage, the Chauvin Arnoux CA745N Digital Voltage Tester can also be used to perform single-pole phase tests. When testing phase or earth the voltage tester will not inadvertently trip highly sensitive RCDs.
Further to this, the CA745N Voltage Tester indicates resistance readings on three thresholds. If a voltage is also detected, the resistance measurements are accompanied by an audible and visual alarm. Additionally, the voltage meter can be used as a continuity tester and will issue an audible signal when continuity is detected.
The Chauvin Arnoux CA745N Digital Voltage Tester features an LCD screen with two bar graph displays. These bar graphs indicate the threshold of each voltage and resistance measurement.
The design of this display makes the Chauvin Arnoux CA745N Digital Voltage Tester easy to read. Adding to this instrument’s ease of use is its compact physical design, which has been optimised for comfortable handling, and its integrated test probe storage compartment.
The test probes are removable and easily replaceable; this, combined with the Chauvin Arnoux CA745N Digital Voltage Tester’s 150-hour battery life, works to ensure this product’s longevity. Furthermore, the user is able to check the tester’s remaining battery power using the battery status check.
The Chauvin Arnoux CA745N Digital Voltage Tester is a durable, easy-to-use, versatile voltage and continuity tester. It is the ideal addition to any electrician’s, heating engineer’s, mechanic’s and maintenance technician’s toolkit.
