4.1 GENERAL PROCEDURES
If the calibration continues to fail due to excessive errors (out of spec), make sure that a molbloc is
properly connected to the molbloc port A and/or B on the molbox and restart the calibration from the
beginning by selecting Check Calibration.
If molbox1 is not auto-detected for whatever reason, the test option is disabled on the main form. Use the
communications menu option to select the proper molbox I/O settings. Before attempting to select any
options, check to make sure that everything is still plugged in properly. To change the settings either
click the settings that you want or tab to the field and use the arrow keys to change the desired item.
Select OK after choosing the proper settings. If you do not know the current configuration, use the
procedure outlined under the Getting Started section (see Section 1.2).
If current (mA) mode calibrations are inappropriately disabled for the molbox1 under calibration, use the
communications menu option to re-establish communications. It is possible the molbox1 style was not
properly detected.
A diagram of the MFC interface cable is included to aid in the reconstruction or modification of the
calibration cable if necessary (see Section 5.5).
