CE/ZERO Key
When the calibrator is in the output mode and you press any of the
numeric keys (0-9), the keystrokes will be displayed until you press ENT
and the value is accepted by the output function. If you make a keying
error, the CE key is used to clear the erroneous entry and allow the
correct value to be re-entered. If you press CE a second time before
entering any numeric data, the keypad display mode is canceled and
the calibrator returns to displaying the actual output simulation value.
When the calibrator is in the input mode the CE/ZERO key acts as a zero
adjustment. This is used when the external pressure module is in use,
but can be used on any Input function. When the key is pressed, the
most recent reading is retained as the “zero point” and all subsequent
readings have the zero point subtracted from them prior to being
displayed.
When the calibrator is displaying a menu, the CE/ZERO key acts as a
CANCEL key to terminate the menu and return to the previous function
or the idle state.
Auto Key
The AUTO key is used in conjunction with the calibration points or
Ramp functions to automatically repeat the function. The Model 135
uses the AUTO key with the “System” function. The time interval
between the automatic repeats is determined by Setup option “Pause.”
The time can range from 5 to 10,000 seconds.
The operation of the AUTO key is covered in detail with the Calibration
Points and Ramp functions.
