3000 Autoranging Digital Multimeter

ACT 3000 Autoranging Multimeter CAT III

The ACT 3000 autoranging multimeter has essential functions specifically designed for testing alarm circuits that some multimeters don’t have. Forexample, it is able to measure induced AC voltage picked up by alarm cables, which if undetected, can cause false alarms. Its robust construction and ease of use makes it the right meter for alarm installers.

• Fully autoranging on resistance, voltage and current, enabling a wide range of measurements to be made without adjusting the switch
• Manual ‘range’ override button allows the user to fix selection on any of its 27 ranges as required
• Extra large 3200 count with bargraph LCD display gives a clear indication of reading as well as polarity, function, over range, data hold and low battery indication
• Includes an ‘Auto-power-off’ function to conserve batteries
• Supplied in a ABS case with flip stand, protective rubber holster, test leads and operating manual
