the range, and the arrow keys
or
must be pressed when you want to proceed to
the following output steps.
By pressing the arrow key , each step will be reached automatically after a
preset time, which is defined through the keys:
1
(10s),
2
(20s),
3
(30s),
4
(40s),
5
(50s),
6
(60s),
7
(70s),
8
(80s) and
9
(90s). These time steps are only enabled once
the arrow key has been pressed, what changes the STEP mnemonic to 0s. Under
this situation, the steps are automatically and continuously scanned. To quit this
mode (STEP set by time), just press the arrow key .
3.8.5. RAMP Programming
By using this programming, the calibrator output varies automatically, thus
producing ramps and level marks which can be programmed to work once or
continuously.
From the main menu, select
CONF
(ENTER),
PRG

and
RAMP
(ENTER). Then you must enter the start and the end values of the range in
which the output will vary (
Setpoint High
and
Low
), and also the value of time (in
seconds) required for a complete ramp within the range (
Ramp Time
). Another value that
may be configured is how long it should dwell at the level mark (
Dwell Time
), i.e., the
time during which the output remains constant between two ramps.
After the configuration is done, go back to the main menu and press
EXEC
; then
the output goes to the starting value of the configured range. When the arrow key
