OPERATIONS
In the MEASURE mode of operation the format of the display varies with the
number of probes present. The user can also modify the display format with
the DISPLAY FORMAT menu. (MENU mode is discussed in Section IV.)
For single-channel operation the entire display area is used as seen in Figure
III-A. For dual-channel operation, Figure 111-B, the display is split in half with
each half dedicated to one channel. For three-channel operation the display
is split into three sections, one for each channel, as seen in figure III-C.
CHANNEL 1 is always the left-most channel in the chassis, CHANNEL 2 the
middle channel and CHANNEL 3 the right-most.
In all cases the display fields contain the same information. Refer to Figure III-
D for the following discussions.
III-B DIGITAL READING
This area 0 contains the reading's polarity, five digits of information
including a decimal point, and the scale (range) of the reading.
In the dc mode of operation the polarity will be "+" or "—" (or blank if the
reading is exactly zero). In the ac mode a sinusoidal symbol will appear (-).
The mode of operation (dc or ac) is selected from the MODE SELECTION
menu.
In the ac mode the reading represents the
true rms
value of the field
waveform.
The user can remove the digital reading from the display using the DISPLAY
FORMAT menu. If this is done the digits and scale will be removed, but the
polarity symbol will remain to remind the user that a dc or ac field is being
measured.
If the CLASSIFIER function has been turned on, the digital field reading will
be replaced by, or alternate with, the phrase "LOW," "HIGH" or "ACCEPT."
See Section IV-K for more information.
