Heater Resistance
Enumeration, Default: 25
The heater resistance field is an enumeration that sets the value of the heater load
resistance. Choices are 50
and 25
. When 50
is selected, the heater will output a
maximum of 50 Volts at 1.0 Ampere or 50 Watts. When 25 Ohms is selected, the
maximum heater voltage is 25 Volts and the output power is 25 Watts.
For additional information, please refer to the
Loop 1 Heater output ranges
or the
Loop 2 Output Ranges
tables.
Warning:
It is necessary to set the Load resistance field to the actual
value of the heater load resistance being used. If an incorrect value is
selected, output power indications will be incorrect non-linear heater
operation may result. If the actual heater resistance is less than
selected, the heater may overheat resulting in an automatic over
temperature shutdown.
Ramping Rate
Numeric entry, Default: 0.10/min
When performing a temperature ramp, the Ramp field defines the ramp rate. Units
