Specifying platinum temperature-measuring resistors
Two types of platinum temperature-measuring resistor
-
the JPt100 (old JIS
type: JIS C1604-1981) and the P t l
00
(new JIS and DIN type: JIS C1604-1989,
DIN 43760-1980)
-
can be used with by A64RDC.
The type of platinum temperature-measuring resistor that is designated in
buffer address 36 is valid for all channels. (Setting done with each Ptl00 is
valid when the power to the PC is turned ON or reset.)
CAUTION
I
Two different types of platinum temperature-measuring resistors cannot be
used simultaneously with one A64RDC module.
If two types are
used,
correct temperature detection cannot be obtained in the channel which is
connected to a different platinum temperature-measuring resistor than the
one specified.
