5.1 Introduction
This chapter is primarily for those users who want to use the monitor
as a stand-alone instrument. But the start-up and alarm relay
sections are also of interest for the PC user.
5.2 Front Panel
The front panel of the monitor is dominated by a 2 x 40 character
fluorescent display screen, 3 Select push-buttons located beneath it
and 5 direction push-buttons (see Fig. 5.1). The rest of the push-
buttons, situated in a line along the bottom, are function push-
buttons.

Small light-emitting diodes (LEDs) are mounted above some of the
front-panel push-buttons. Their function is to inform you of the
operating state of the monitor. For example, if the LED above the
MEASURE push-button is lit, it indicates that the Monitor is either
busy performing measurements or has been set-up to start
measurements at a pre-defined time.
5.2.1 Direction Push-buttons
This group of 5 push-buttons is referred to in this manual as the
direction push-buttons.
▲ & ▼ have two uses: to increase & decrease numbers, respectively,
or to go to the Previous & Next Displays, respectively.
