Change Display Intensity Level; Print Request; Output Set; Output Hold - Omega Engineering PTC900 User Manual

CHANGE DISPLAY INTENSITY LEVEL

When activated (momentary action), the display intensity changes to the next
intensity level (of 4). The four levels correspond to Display Intensity Level
( ) settings of 0, 3, 8 & 15. The intensity level, when changed via the User
Input/Function Key, is not retained at power-down, unless Quick Programming
or Full Programming mode is entered and exited. The unit will power-up at the
last saved intensity level.
Note: The next two parameters only appear when an RS232 or RS485 Serial
Communications Card is installed in the meter.

PRINT REQUEST

When activated, the meter issues a block print through the serial port. The
specific values transmitted during a print request are selected with the Print
Options parameter in Module 7. For User Inputs (level active), the meter
transmits blocks repeatedly as long as the input is active. For Function Keys,
(edge triggered) only one block is transmitted per key press.
PRINT REQUEST and RESET (Edge Triggered)
When activated (momentary action), the meter first issues a block print
through the serial port, and then performs a Momentary Reset on the displays
entered as in the sublist. The specific values transmitted in the print block
are selected with the Print Options parameter in Module 7. Only one transmit
and reset occurs per User Input activation or Function Key press.
