3.3 CONTROL PANEL AND OPERATING DISPLAYS
The operating displays appear both at the recorder display and at a hand-held terminal if fitted. The hand-held
terminal can display only 16 characters, resulting in the loss of the last 4 character positions from the 20-char-
acter recorder display.

3.3.1 MEASURED VALUE DISPLAYS
There are two types of operating display: Multi-channel and Single channel. After initialisation is complete, the
multi-channel display is presented, showing Channels 1, 2 and 3 with channel number, measured value and
units-of-measure.
MULTI-CHANNEL DISPLAYS
There will be two Multi-channel displays for 4, 5 or 6 channels and three displays for 7, 8 or 9 channels. If all
three channels in a display are turned OFF (see section 4 - channel function), that display will not appear.
Multi-channel displays scroll to the next higher group every 12 seconds. Operation of the ENTER key causes
the scroll to stop, holding that particular display until another key is operated.
The down arrow key can be used to step through all multi-channel displays; the up arrow key can be used to
step through all the multi-channel displays, followed by all the single channel displays.
