The function SC will show IN or NO. Confirm IN to configure the scaling or NO to
disable the SC function, with the key ENTER.
The scaling is performed via the INPUT HIGH and INPUT LOW parameters,
corresponding to the maximum and minimum values of the calibrator signal input, in the
engineering unit of this signal. Next, configure the SCALE DEC (0-4), SCALE HIGH and
SCALE LOW parameters according to the maximum and minimum values of the
transmitter scale and the desired number of decimals. The scaled value is shown on the
display with the # unit.
For example, temperature transmitter with 0 to 100 °C input and 4 to 20 mA
output. The scaling with one decimal would be:
INPUT HIGH: 20.0000 mA
INPUT LOW: 4.0000 mA
SCALE DEC (0-4): 1
SCALE HIGH: 100.0 #
SCALE LOW: 0.0 #
MEM: The T-650PH calibrators allow many special programs and functions that
can be of frequent use. In situations like this, it would be useful to store the current
configuration in memory in order to save time. Up to 8 configurations can be stored in
memory.
Selecting the option MEM, it is possible to store the current configuration
(WRITE), restore a previous stored configuration (RECALL) or erase the 8
configurations from memory (CLEAR ALL).
Selecting the option WRITE or RECALL will present a new menu with numbers 1
to 8, representing each one of the memory positions. Choose one of the positions and
press ENTER. The writing operation (WRITE) can be made in an already used memory
position. The calibrator asks for the overwriting confirmation with the message
OVERWRITE MEMORY?. The CLEAR ALL operation shows a confirming message
ARE YOU SURE?. In both cases, press ENTER to confirm the operation or C/CE to
cancel.
