6.3 – TRANSMITTER INPUT CALIBRATION
6.3.1
Transducer Calibration
Minimum and maximum full scale differential pressure will be applied to the MASS-tron II/CEM, unit will be programmed
to recognize these pressures as zero and span for transmitter input calibration.
1. While in Main Menu, scroll to:
Transmitter Input
Calibration
2. Press
ENT
, and display will indicate:
Transducer Zero
Calib: 0.00 in.WC
3. Press
ENT
, and display will indicate:
Transducer Zero
-- Push ENTER --
4. Press
ENT
, and display will indicate:
Transducer Zero
Settle Time:4 Sec
Display will count down to 0, after which it will indicate:
Input Zero Done
-- Push ESCAPE --
5. Press
ESC
and then
UP
, display will indicate:
Transducer Span
Calib: X.XX in.WC
6. Apply input pressure (as read on manometer) to the High port of the MASS-tron II/CEM. Adjust pressure to
equal the transducer natural span value, which is indicated on the display.
7. Press
ENT
, and display will indicate:
Transducer Span
-- Push ENTER --
8. Press
ENT
, and display will indicate:
Transducer Span
Settle Time:4
Display will count down to 0, after which it will indicate: Input Span Done
-- Push ESCAPE --
Note:
If pressure input is less than 40% or greater than 110% of transducer's natural span value (see
Factory Set-Up Information Sheet), display will indicate:
Bad Input Span
-- Push ESCAPE --
If this occurs, check input pressure (as read on manometer), and readjust as necessary. Press
ESC
and
repeat Steps 6 through 8.
9.
Press
ESC
.
10. Remove input pressure from High port on MASS-tron II/CEM.
