Selecting A Meter Type

The following example explains how to select a dual-channel clamp-on meter and initiate site program-

ming for the measurement channel. Your [Meter Type] selection, as well as other menu selections, are

“remembered” through power cycles.

NOTE: If you have a single-channel system, all you have to do is select a measurement tech-

nology and then go directly to Channel Setup. The site setup procedure for a single-

channel system is identical to setting up a measurement channel on a dual-channel

system.

As shown in the steps below, selecting this mode only requires key presses. This

is because dual-channel clamp-on is the default configuration for this instrument. To

select a different configuration, move the cursor to the desired Meter Type and then

press to select it.

Make sure that the keypad enable switch is in the [Enable-Up] position. Turn on power

and press to access the [Meter Type] screen. Refer to the figure below.

Note that on the left-hand column, [Meter Type] is highlighted as are all the available

meter types on the right-hand column. Press . This places a cursor next to [Dual-

Channel Flow].

ment task. User output data, however, is mostly reserved for the virtual or system channel. This in-

cludes the totalizer functions. Analog data is largely reserved for the virtual or system channel as well

as the totalizer functions, analog outputs and datalogger. In some instances, access is also provided

to the path channel’s data in order to facilitate the gathering of diagnostic information; thus minimizing

menu clutter, but preserving as much functionality as practicable. Totalizer control via lead-in function

key is provided by F3 (dual-path meter) and, since there is no F5, F1 (four-path version). The Diagnos-

tic Menu area has been similarly setup to provide data (Path 1, Path 2 and Path 1 and 2) generated by

the physical measurement channels when selected, but, to suppress elements only provided by the

virtual channel. As mentioned above, use a partially installed multipath site in order to direct all meter

input/output to a single measurement path. Simply install the single available physical path and you’ll

produce data based on only this physical input and obtain the same functionality as provided to the

single channel user.
