8.9 GENERATING A TEST CURRENT
8.9.1 Purpose
This section describes how to generate output currents for testing recorders and data han- dling systems.
PROGRAM
SIM OUtPUt
EXIT NEXT
8.9.2 What happens while the transmitter is generating a test current?
1.The output current goes to the programmed test value and remains there until the TEST function is disabled.
2.The main display continues to show the pH of the process stream. The word HOLD appears in the display.
3.The test current value supersedes both the HOLD value and the FAULT value.
4.If a fault occurs while the transmitter is generating the test current, the word fault appears in the display and the display flashes.
8.9.3 Procedure
1. Press PROG on the infrared remote controller (IRC).
ENTER 
2. Press NEXT until the SIM OUtPUt
PROGRAM
tESt
EXIT
12.00
ENTER
3.The tESt prompt appears. Use the editing keys to change the number to the desired value. The allowed values are between 3.80 mA and 22.00 mA.
