I-bar tabs to open, 2) place the wire in the CTV window, 3) snap
the I-bar closed.
•The I-bar on the CTV-D and CTV-E units is fully removable for
easy installation. Make sure the I-bar is replaced in the proper
orientation to ensure correct readings. The contacts on the unit
and I-bar are marked with matching notations.
•The CTV-A, -B, and -C units are provided with a snap-on
mounting plate which can be removed from the CTV and
