3.6.1 Point Tag

The Point tag is an alphanumeric indication of what the point represents and is generally located or displayed
at the bottom of the bar graph or on the chart itself. This information is also stored to disk/card to uniquely
identify the point.
To add a Point tag:
1. From the Point Setup menu use the UP (↑ ↑ ↑ ↑ ↑ ) or DOWN (↓ ↓ ↓ ↓ ↓ ) button to highlight Point tag and then press the
ENTER button.
2. You will be presented with the first page of an alphanumeric keypad. There are four pages available which
include all the upper and lower case alphabet characters, numerics and various signs and symbols for
programming engineering units. Up to ten characters for the point tag may be entered (only eight will be
displayed on the screen). To access characters on another page, simply press the PAGE button. The
space button is "SPC", the LEFT (← ← ← ← ← ) and RIGHT (→ → → → → ) buttons move the cursor to the position you wish
to edit or enter.
3. Use the letter/symbol buttons to program the Point tag as "EXAMPLE" and then press the ENTER button
to return back one menu. To exit without programming a tag, press the EXIT button to return to the Point
Setup menu.
The way data is displayed on the chart or recorded to disk/card is a function of three things: the input scale, the
output scale and the chart scale. These may be programmed independently to provide a full scale output of any
range of the input.
