Sierra Instruments Instruction Manual
Smart-Trak
®
2 Series 100
65
The instrument will display its current full-scale value. If your instrument is new or
this value has never been modified, the value displayed will be 100% of the
maximum flow rate your Smart-Trak 2 can measure or control without factory re-
calibration. This is the number listed here:
The instrument’s maximum flow rate is also recorded on the data label (at the back
of the instrument) and on the calibration certificate.
You may select any full-scale value between 100% and 50% of the maximum full-
scale value. If you select a new full-scale value, it will re-define the analog outputs
of the instrument. The 20 mA signal and the corresponding voltage signal (5 or 10
VDC) will now represent this new full-scale value.
To change the full-scale value of your device, modify one digit or erase the current
value displayed and type in your desired full-scale value. When you are satisfied
with your selection, press the enter key. The new full-scale value will appear in the
white box. A few seconds later, the same value will appear in the yellow box in the
upper half of the screen titled “Full Scale.”
