Key
1 When ramp
ready appears at the display:
Start the sequence by pressing
2 Stop the falling ramp within fall time t3 with the  or the 
key.
3 Start a rising ramp within remaining fall time t3 with the  key.
4 Stop the ramp sequence by pressing the  or the  key.
5 Start a falling ramp with the  key, remaining dwell time t2 is
cleared.
6 Stop the ramp sequence by pressing .
6.7.3 Dual Mode (simultaneous simulation and measurement)
All simulation functions can be activated and, at the same time,
transmitter signal U or I can be measured in the most commonly
used measuring ranges (30 V DC or 30 mA DC) in the dual
operating mode.
Special case: simulation and measurement of voltage or current
without an external circuit. For example, if voltage output needs to
be tested, you only need to connect the Calibrator+ and Sense+
sockets to each other, because the Calibrator– and Sense– jacks
are connected internally.
Activating the Dual Mode
Ð Select a simulator function with the rotary switch. The calibra-
tion operating mode must be activated (see section 6.1).
Ð Press and hold the ZERO / SEL | ESC key for approximately 2
seconds, and select the U
dc
or I
dc
measuring function with the
  keys.
Ð Press the OUT | ENTER key in order to acknowledge your
selection.
Ð Depending upon the calibration function, select either the
simulator range or the sensor with the ZERO / SEL | ESC key.
Ð Set the simulation value in the main display with the
  keys.
Ð Activate the output by pressing the OUT | ENTER key.
The respective measured values appear in the left-hand auxiliary
display, and DUAL appears to the right of the measured values.
Ð Exit the “dual mode” function by turning the rotary switch, or
by pressing and holding the ZERO / SEL | ESC key for
approximately 2 seconds, selecting OFF in the menu with the
  keys and acknowledging with OUT | ENTER.
