Martel Electronics 235 - Manual (Page 59)

Calculate the ramp time to achieve a desired resolution using this
formula.
ramp time = (ending value – starting value)
(step size x 4)
Auto Mode
This function continuously repeats the calibration points or output
ramp programs. If the ramp function is active when the AUTO key is
pressed the ramp function is cycled continuously. If trip detect was
enabled, it is canceled by the auto mode. If the ramp function is not
active, then the CalPts are cycled repeatedly. If CalPts were not
enabled, no action is taken.
mA/V Module (Optional)
The 20 Milliamp/10 Volt Output Module is an accessory for the Model
230/235 calibrator to allow it to generate either 0-20 mA or 0-10 volt
outputs.
Installation
The module attaches to the calibrator’s feature connector at the base
of the calibrator. The connector is keyed to prevent improper
installation.
The module may be installed when the calibrator is turned on without
causing any damage to the calibrator or module. The preferred
installation method is to attach the module to the calibrator while the
unit is turned off. This allows the module to initialize properly as the
calibrator is turned on, the module should be initialized by pressing the
OPT key before continuing to use normal calibration functions.
Operation
The module is activated by pressing the OPT key on the calibrator
keypad while the calibrator is in the output mode.
