Auto Ramping the mA Output
Auto ramping gives the ability to continuously apply a
varying current stimulus from the meter to a transmitter,
while hands remain free to test the response of the
transmitter. Select either sourcing or simulating by choosing
the SOURCE or SIMULATE jacks.
When the rotary function switch is in the OUTPUT mA
position, and the output jacks are connected to an
appropriate load, the meter produces a continuously
repeating 0 % - 100 % - 0 % ramp in a choice of four ramp
waveforms:
0 % - 100 % - 0 % 40-second smooth ramp
0 % - 100 % - 0 % 15-second smooth ramp
0 % - 100 % - 0 % Stair-step ramp in 25 % steps,
pausing 5 seconds at each step. Steps
are listed in Table 3.
The ramp times are not adjustable.

n. Loop Power Supply Mode
The Loop Power Supply Mode can be used for powering up
a process instrument (transmitter). While in Loop Power
Mode, the meter acts like a battery. The process instrument
regulates the current.
