•
For example, after the sensor is properly confi gured, send the following
Command Packet to confi gure the instrument with a resistance setpoint
of 10 k
Ω
.
Write
!010.00023
(Sets [SET R] in k
Ω
)
•
To read the instrument’s setpoint resistance, the Command Type changes
from a WRITE (2) to a READ (1):
Read
!000.00021
(Reads [SET R] in k
Ω
)
•
Resistance Setpoint ranges from +000.000 to +499.900 k
Ω

To use resistance as the setpoint, you must be using a resistive sensor:
thermistor or RTD. The following table shows the confi guration settings
and
Command Packets to set the confi guration for a thermistor or RTD
in resistance mode.
