9.1.6 How to Set the Sampling Interval for Rate-of-change Alarms
You can change the sampling interval for rate-of-change alarms by the following setting
(common for all alarms).
The initial value is ‘01’ sample (the actual time depends on the model and A/D
frequency; see also table 9.1 on page 9-9).
Figure 9.4
If you want to change the sampling interval for rate-of-change on increasing signal:
SETTING PROCEDURE:
Enter the SET UP Mode by turning ‘ON’ the power while pressing and holding the
ENT-key until the SET UP display appears.
Use the UP/DOWN-keys to select the display ‘SETUP=ALARM’. Press the ENT-key.
Press the ENT-key until the display ‘R_TIME=1’ appears. Select the sampling interval
(min. is 1 sample interval, max. is 15 sample interval). After selection, press the ENT-
key.
The setting has been completed, but has not been stored yet.
Before leaving the SET UP Mode, you have to store your new settings. Proceed with the

to the ‘SETUP=ALARM’ display and then select the ‘SETUP=END’ display.
Press the ENT-key. Select ‘END=STORE’ to keep your new settings or
