English Instruction SheetPanel 7

Auto Ramping the mA Output

Auto ramping allows you to continuously apply a varying current from

the Calibrator to a passive (sourcing) or active (simulate) loop. Your

hands remain free to test the transmitter’s response.

Press B + C simultaneously to enter the Auto Ramp mode and

step to a ramp type.

The Calibrator applies or controls a continuously repeating mA signal

over a 0-20 mA or a 4-20 mA span in one of three ramp types:

Slow (e) 0 % to 100 % to 0 % smooth ramp over 40 sec.

Fast (g) 0 % to 100 % to 0 % smooth ramp over 15 sec.

Step (f) 0 % to 100 % to 0 % stair-step ramp in 25 % steps,

pausing 5 sec at each step.

To exit, press any pushbutton or turn the Calibrator off.

Using the SpanCheck Function

The SpanCheck™ function checks the zero and span points of a

transmitter in either SOURCE or SIMULATE mode.

To select SpanCheck, press C.

To exit, press any pushbutton or turn the knob.
