4.7.5 Stopping a sweep
1 Tap Control on the Home page. The Control Loop Configuration page is displayed.
2 Select the required temperature sensor from the list in the Sensor parameter box.
3 Tap the Set point button until it displays Fixed . The Set point parameter box value is held
at its current value.
4.8 Using the ramp function
4.8.1 The purpose of the ramp function
Firmware version 1.4.40 introduced additional functions to provide set point ramps. A ramp rate
is set in K/m (Kelvin per minute) and when the ramp mode is enabled, any change in the set
point will occur at this rate.
4.8.2 Using the ramp function
Ramp mode can only be enabled (or disabled) by remote SCPI commands.
The mode is control loop specific so for iTCs with multiple PID control loops configured, setting
one of them into ramp mode will not set the others into ramp mode. To use ramp mode, follow
these steps.
1 Send a remote command to set the desired ramp rate (K/min)
SET:DEV:MB1.T1:TEMP:LOOP:RSET:5.25
This command sets the ramp rate to 5.25K/min for the control loop controlled by the MB1
temperature sensor input. The system returns
STAT:SET:DEV:MB1.T1:TEMP:LOOP:RSET:VALID
2 Send a remote command to read the temperature
READ:DEV:MB1.T1:TEMP:SIG:TEMP
The system returns
STAT:DEV:MB1.T1:TEMP:SIG:TEMP:xxx.xxxxK
where xxx.xxxx is the value of the temperature.
