USER'S MANUAL
LR-24 ELECTRODE POLE TESTING
1. Connect an ohmmeter to the two pins labeled in the
larger connector (
Fig. 8.1
). The meter should read 0
ohms.
2. Leave one lead of the ohmmeter connected to one of
the pins in the large connector and connect the other
lead of the meter to the metal socket in the bottom end
of the pole. The meter should read 0 ohms.
3. Connect the leads of the ohmmeter to the pins of
the small connector. (
Fig. 8.2
). The meter should read
infinite ohms.
4. Press the operator switch down against the rubber
handle of the pole. The meter should read 0 ohms.
If the pole fails any of the tests above, the pole needs to
be replaced. If the pole passes all of the tests above, then
the problem is in the LR-24 and it should be returned to
the factory for repair.
LR-24 CATHODE TESTING
1. Set the multi-meter to measure resistance and
connect leads to the pins of the connector on
the end of the cathode cable. The meter should
display close to 0 ohms between the 2 pins.
2. Move one of the leads to the bare metal cable.
Again the meter should display close to 0 ohms
between the pin in the connector and the bare
cable. Flex the cable along its insulated length
and watch the meter reading as you do. Be careful
to keep the ohmmeter securely connected while
flexing the cable. If the meter reading changes
significantly or jumps, the cable should be replaced.
