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
).
WRITE
RECALL
CLEARALL
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.
