Newport 8000 - Local Operation Thermistor Calibration; Remote Operation Thermistor Calibration

Chapter 6 Calibration 79
6.3.2 Local Operation Thermistor Calibration
a. Measure and record the exact resistance of your metal film resistor. Use
nominal values of 20 kΩ for the 100µA setting, and 200 kΩ for the
10µA setting. With the TEC output off, connect the metal film resistor
to the sensor input of the TEC Module.
b. Go to the single module display by first pressing the
MENU
button,
then the
Modules
soft key, then the slot soft key that corresponds to the
module to be calibrated.
c.
Press the
Setup
soft key and select the appropriate thermistor (10µA or
100µA) as the Sensor Type. Press the
Prev
soft key to return to the
single display.
d.
Go to the Calibration Screen. This is done by pressing the
Menu
button,
Config
soft key,
Calibrate
soft key; then the soft key(s) that
correspond to the module to be calibrated.
e. Enter the TEC sensor calibration mode by pressing the
Sensor
soft key.
Follow the on-screen instructions to complete the calibration. The
calibration can be canceled without affecting the stored constants if the
Cancel
soft key is pressed at any point prior to completing the
calibration.
6.3.3 Remote Operation Thermistor Calibration
a. Measure and record the exact resistance of your metal film resistor. Use
nominal values of 20 kΩ for the 100µA setting, and 200 kΩ for the
10µA setting. With the TEC output off, connect the metal film resistor
to the sensor input of the TEC Module.
b. Enter the
TEC:CHAN
command to select the channel [,suchannel] to
be calibrated. Send
TEC:SENS 1
100µA thermistor, or
TEC:SENS 2
for the 10µA thermistor, followed by the
TEC:CAL:SEN
to enter
sensor calibration mode.
The 8000 will be ready to receive the resistance when, after a
TEC:CAL:SEN?
query is sent, a “1” is returned.
c. Input the actual resistance of the metal film resistor, in kΩ, (as an <nrf
value>) via the
TEC:R <nrf value>
command.
If, at any time prior to
TEC:R,
a command other than
TEC:R
or
TEC:R?
is sent to the 8000, the 8000 will cancel the calibration mode
