There is a need to test primary batteries to see how much life remains in the field. This PSM-13 primary battery tester is designed to be carried on the soldiers belt.
The TS-183 is a primary battery tester designed for use at the depot level or higher (in a lab environment).
The set consists of the following items: TS-1301 Test Set, U-240, U-241, U314, U315, U-347, U-410 adapters and the CS-842 canvas carry bag. The test set contains a 1 ma full scale meter marked red, yellow and green and a switch to make various connections to the 8 pin plug recessed on the side of the tester opposite to the meter. The battery adapters typically contain load resistors and voltage dividers and/or Zener diode so that the meter will read properly for the section of the battery being tested.
All of the adapters have an octal tube socket on one end (see the U-410 in the photos above) that mates to the recessed octal plug on the TS-1301 The U-241 adapter has the U-242 pin straighter/protector attached by a string.
WARNING - Do not use this adapter to try and test the BA-5598/U LiSO2 battery. Doing so may result in causing the battery to vent and/or burning out the U-410 adapter.
Connect the appropriate adapter to the battery tester and insert the adapter into the battery.
Note: When used on the BA-4386 the tester activates the battery and then the battery will have more output than it would have if only connected to the radio without first applying a heavy load. I suspect that radio operators who had access to the PSM-13 would use it prior to installing a new battery to activate the battery. If you know about this tell me.
