Running Pulse Probe Unit Cabling
Run pulse probe unit cable from the meter to the meterwatch
unit. Use stainless cable ties to keep the cable in place or run the
cable in a conduit. The connector fits through a 25mm conduit.
Pass the connector through the stainless-steel tamper bracket as
shown here.
(The tamper bracket will be fitted to meterwatch later.)
Plug the connector into the microSpider input (the one with no red ring) and tighten the ¼ turn
locking nut.
