Electrical
Continuous Real-time Electrical Tests Active fault identification with audible alarms: direct circuit activation at the tester and via the optional full-function remote control. The electrical activity on each circuit selected is cntinously compared to the electrical activity on all of the other circuits.
All Circuit Autometed Test Sequentially activates each individual circuit while monitoring the electrical activity of the other circuits. The tester then displays the results on the built-in LCD panel. Audible alarms are present during the testing process
All Circuit Load Test Allows multiple ciscuits to be made active at the same time. The trailer's cumulative current draw is displayed. Note: In this operating mode, the real-time diagnostic circuitry and software is inactive.
Direct Fault ID (default mode) Identifies OPEN SUPPLY, OPEN GROUND, SHORT, and CHASSIS SHORT via 7-way connection - "Active" fault identification circuitry and software senses intermittent electrical problems, and the tester's display readings and audible alarms are updated on a real-time basis
Volt, Amperage Meters Digitally monitors tester output voltage and trailer amperage in both single and multi-circuit modes
Audible Alarm Unique alarm for each of the four fault types
Max Amperage 18 Amp maximum load (The amperage threshold for the identification of a chassis short is approximately 15 amps)
Software PRO-CHECK version 1.0.1
ABS Circuit Test The AUX circuit powers the ABS activating the ABS warning light and ABS solenoids.  If the warning light turns on, the ECU and light is working. If the warning light turns off, there are no current ABS faults. The Auxiliary circuit is also tested as part of the automated test, and can be directly switched from both the tester control panel and the full-function remote
