5) Set the Ohmmeter to its highest range (R x 10,000) and measure from wire lead M1 or MR to the
meter body (case ground). The resistance reading should be infinite. If this measurement is less than
100 K ohms, the meter is defective and must be replaced.

When all measurements appear normal, the coil wires can be reconnected and the meter can be
returned to service. As applicable, re-install the integrally mounted Signal Converter and/or replace
meter housing cover.

6.3.2 Electrode Check

The electrode check is essentially a resistance measurement that can be made to establish that a
short (or high resistance leakage path) does not exist between one, or both, electrodes and ground.

Before proceeding, verify that system power has been de-energized. To perform this test, the meter
must be removed from the pipeline and the meter liner "wiped" dry. When the meter liner has been
thoroughly dried, proceed as follows:

1) Remove field wiring connected to electrode leads "1" and "2". Proceed to step 2). Elec-
trode wiring is shown in Figure 5-1.

2) Place Ohmmeter on highest available range (for example, R x 10,000).

3) Connect the Ohmmeter "minus" lead to the meter ground stud and the "plus" lead to elec-
trode line 1. This reading should be infinite. If any resistance can be measured, the meter
is defective and must be replaced.

4) Check the other electrode by connecting the Ohmmeter "plus" lead to line 2. This read-
ing must also be infinite. If any resistance can be measured, the meter is defective and
must be replaced.

5) If measurement of both electrodes indicate an infinite resistance reading, the meter may
then be returned to on-stream operation after wiring has been restored. Re-install the hous-
ing cover and place meter in operation.
