is +0.006° at -200°C and -0.006° at +850°C.
The input must be the ratio Rs/Ro, where Rs is
the RTD resistance and Ro the resistance of
the RTD at 0°C (Sections 7.9 and 7.10).

*** 17 INTERNAL TEMPERATURE ***
FUNCTION
This instruction measures the temperature (°C)
of a thermistor on the CR10 analog board. This
temperature is generally not adequate for use
as the thermocouple reference temperature
(Section 13.4).

*** 18 MOVE TIME TO INPUT LOCATION ***
FUNCTION
This instruction takes the current time in
seconds into the minute, minutes into the day,
or hours into the year and does a modulo divide
(see Instruction 46) on the time value with the
number specified in the second parameter.
The result is stored in the specified input
location. Entering 0 or a number which is
greater than the maximum value of the time for
the second parameter will result in the actual
time value being stored.

*** 19 MOVE SIGNATURE INTO INPUT ***
LOCATION
FUNCTION
This instruction stores the signature of the
Read Only Memory (ROM) and user program
memory (RAM) into an input location. The
signature is a result of the CR10 PROM, the
size of RAM, and the entries in the *1, *2, *3,
*A, and *C Modes. This signature is not the
same as the signatures given in the *B Mode.
Recording the signature allows detection of any
program change or ROM failure.

*** 20 PORT SET ***
FUNCTION
This instruction sets or configures specified
control ports (C1-C8). On power-up, ports
default to input configuration (i.e., they are not
driven high or low by the CR10, and can be
used to read the status of an external signal
using Instruction 25). When a port is set high,
low, pulsed, or toggled by this instruction or a
program control command, the port is
automatically configured as an output.
NOTE: Voltages in excess of 5.5 volts
applied to a control port can cause the
CR10 to malfunction.
Ports can also be set using the *6 Mode or the J
and K telecommunications commands. However,
the ports MUST be configured as outputs before
these means of setting them will work. The
option to configure the port as an output is used
when a port must be configured as an output
without changing the state of the port.
