Type MET electronic recloser control tester operating instructions
Appendix B
Special battery-testing cable and adapter
(catalog no. KA11 14ME)
The special battery-test cable enables the MET tester to
check battery voltage and charge/discharge rates of early
Form 3 controls (below serial number 10649) which have
only two bat- tery-test-terminal posts on the front panel.
With the addition of a set of adapters to the special
battery-test cable, the battery voltage and charge/discharge
rates of all Form 2 controls (which do not have a separable
battery plug and receptacle) can also be checked. Color-
coded leads and the combination of male and female plugs
on the adapters and test cable assure proper polarities
when connecting to the test set.
Form 3 controls below serial number 10649
1. Swing out the front panel of the ME control and
disconnect the battery plug from its receptacle.
2. Connect the male CONTROL plug of the special test
cable into the battery receptacle in the control.
3. Connect the battery plug into the other (female) plug of
the test cable (Figure 6).
4. Connect the other end of the battery test cable to the
BATT. TEST TERMINALS on the MET tester. Make sure
all three pins of the test cable plug are engaged.
5. Perform the BATTERY TEST procedures as specified on
Page 5 of this manual.

of the tie board on the back of the front panel.
3. Connect the leads of the adapter on the CONTROL
plug to the BATTERY terminals on the tie board.
A. Male connector (red lead) to (+) terminal.
