Scaling
Cyclic
scaling print
The scaling can be printed in two different ways:
cyclic:
for each channel, at a configurable spacing
(Configuration level 2
triggered:
for each channel, when the F-key is pressed for at least 4 sec, or by closing a
logic input
(Configuration level 3
The basic rule is: scaling can only be carried out when the plot status is acti-
vated for the corresponding channel.
Selectable spacings:
- approx. 30cm
- approx. 60cm
- approx. 90cm
- switched off
The scaling is printed in the colour selected for the channel. In the bottom line
is the programmed channel designation and the dimensional unit for the
measurements.
If the presentation range of 0 — 100mm has not been altered, then the scale
marks for 0%, 50% and 100% levels will be in the second line. If the presen-
tation range has been restricted, then "I" marks will appear in this line, which
indicate the start and end of the presentation range. The corresponding nu-
merical values will be shown in the next line.
Limit marks ("I") for the channel concerned will be printed in the top line.
The limit marks are the threshold levels for the limit comparators, which are
programmed with the aid of the parameter Configuration level 1
parator
Limit value. The correlation between measurement channels and the
limit comparators is set up in the parameter Configuration level 1
parator
Channel.
The limit marks are only printed if the corresponding limit comparator is active,
i.e.:
- Limit-text state = ON
(Configuration level 1
or
- Open-collector output 1 — 3 = ON
(Configuration level 2
or
- Relay output 1 — 8 = ON
