If Auto calibration was successful, you will be directed out of the calibration

menu to the operational display without viewing any further scrolling messag-

es. (To proceed to step 6.4, you must select SKIP at 6.3A.)

If calibration fails, _ _ _ CALIBRATION FAILED will scroll across the display and

you will be directed back to the operational display. The most likely cause of this

error is that the controller could not detect any change in input signal during

calibration. Check your signal and connections, and repeat the procedure.

Manual calibration

_ _ _ ENTER DISPLAY VALUE FOR [LOW MA/V] scrolls across the display, and

toggles with the current low display value. Use the

the display value for the low level input signal. Then press

The text string for [LOW MA/V] is determined by your INPUT MODE (selected in 6.2C):

0MA (for 0-20mA), 4MA (for 4-20mA) or 0V (for 0-2V/0-10V).

_ _ _ ENTER DISPLAY VALUE FOR [HIGH MA/V] scrolls across the display, and

toggles with the current high display value. Use the

the display value for the high level input signal. Then press

The text string for [HIGH MA/V] is determined by your INPUT MODE (selected in 6.2C):

20MA (for 0/4-20mA), 2V (for 0-2V) or 10V (for 0-10V).

Manual calibration is now complete. You will be directed back to the opera-

tional display. (To proceed to step 6.4, you must select SKIP at 6.3A.)

Specifi c gravity scale factor

_ _ _ SPECIFIC GRAVITY scrolls across the display, and toggles with the specifi c

gravity scale factor. Use the

and then press

Specifi c gravity scaling now complete. You will be directed back to the opera-

tional display. (To proceed to step 6.4, you must select SKIP at 6.3A.)

Note that altering the SPECIFIC GRAVITY scale factor does not constitute a

full calibration, and assumes that either AUTO or MAN calibration has been

applied previously with the S.G. value set to 1.0.
