OPTIONAL MONITORING OF MULTIPLE LOADS
The Veris 6001 is extremely flexible and allows multiple
sets of current sensors to be used in parallel so that
multiple locations can be monitored by a single meter.
This allows for a totalized output from two or more
locations.
RULES FOR ACCURATE PARALLEL INSTALLATION
1. Current sensors must be installed in complete sets of
three (3) when used for paralleling. This is necessary when
paralleling poly- with single-phase sources.
2. All parallel current sensors must be of the same rating
(i.e., all 100A.).
3. All locations being monitored must have the same
power source. Even with identical voltages, you must not
violate this rule.
4. The outputs registered by the KWmeter (i.e., the 4-
20mA scale , KWH/pulse, and any displays) must be multi-
plied by the number of CT sets. (i.e., if your KWH/pulse
value is 0.5 KWH/pulse with only one set of CTs, then with
three sets your new KWH per pulse = 0.5 x 3 = 1.5.
