¶ TestMon Commissioning Tool
The TestMon is used to test relevant voltage to ensure that the wiring is not in the wrong sequence.
It is not meant to be precision equipment.
The device is initially used to check and validate the wiring loom before plugging into the WathcMonPlus/WatchMon5 (WM5), which is now a legacy supervisor. All WatchMon5 starter kits used to come with a TestMon.
With the new supervisor (WatchMonCORE) and cell monitor (CellMate-K9), the use of TestMon is not essential but can be purchased along with the starter kit if desired.
¶ Feature
- Battery cabling and cell voltage tester for 10 - 15 series packs
- Used before plugging into the supervisor
- Temperature sensors are also provided with the TestMon to allow the remote monitoring of the cells in 3 separate locations.

¶ TROUBLESHOOTING: TestMon
¶ Passes. And then, Gives a Fail
We have had some feedback that the same wiring can fail due to a jumper, but then on the next press of the button, it says "pass".
When doing the quick test and the TestMon doesn't get the result in time, it sees this as a failure and hence gives a "fail". If you get one pass then that should be taken as good. Just repeat the test a few times.
UPDATE: We have adjusted the TestMon firmware to eliminate this error.
¶ Error on Jumper
In some instances rather than reading 0V for the position of Jumper, it reads -0.01V instead, which causes a problem.
Try to measure each cell or run through the Volt readings on the TestMon.
¶ LTO Batteries with TestMon
Unfortunately, TestMon was designed with regular Lithium batteries in mind and isn't separately powered. It gets its power to run from the first battery connected. Therefore if that cell 1 is too low then the TestMon won't function. This is an intermittent problem - if the first battery in line is charged up then it will function, but at half power, it won't.
To get around this limit, it can be manually checked with a voltmeter on each pin to ensure that the wires haven't been crossed and each cell is measuring in the valid range.
