calibration or to recalibrate the instrument is with a CLAUSTEMP
®
Model HIP Handheld Pyrometer. See
www.claustemp.com
.
To calibrate the HIR Pyrometer:
1.
Measure reactor temperature using a CLAUSTEMP
®
model HIP handheld pyrometer or other means.
2.
Ensure Model HIR has a clear sight path into the reactor.
3.
Press and hold the NEXT button while simultaneously pressing the UP arrow button. Then release both
buttons.
4.
Press the NEXT button to display the CAL TEMP parameter.
5.
Unlock the calibration feature by pressing and holding the NEXT button while simultaneously, pressing
the DOWN arrow button. Then release both buttons.
