Procedure

1. Make sure that the spin controls

for Tube and Bulb are both set

to “1”:

This corresponds to the left-hand tube in the left-hand bath and the
bottom bulb in the tube.

2. Check the values for the calibration constant(s) as they appear at the

bottom of the window:

The Calibration window

Compare these values to your archive of the calibration constants (if
available) for tube 1 and bulb 1. The values should be identical.

3. If they are not, place your cursor in the appropriate field, delete the

entry, then type the correct values for the constants in the text boxes.

4. Click Update bulb.

5. Use the tube and bulb spin controls

to select the tubes/bulbs for

which you noted calibration constant errors. Input the correct values
for each. Make certain to click Update bulb after you have corrected
C and E calibration values for each bulb BEFORE selecting the next
tube and/or bulb.
