3.7 TEST: TEST SET VALUE (SHORTCUT: CTRL+T)
The purpose of the Test Set Value option is to allow a user to insure that the values between the
calibration points are within the molbox1 specifications. Values set with this option are corrected by the
molbox1 sense line, while the set values of a Calibration Check are not. When selected, a form is
activated that allows users to select the mode and enter a desired set point and read the circuit output
(see Section 5.3). To set a value, choose the desired set mode and enter the desired value and press
either enter or send, then enter the multimeter reading when prompted. The percentage of full scale error
of the sense and measure outputs display next to their corresponding values. The status bar at the
bottom of the screen will display “Out of spec…” or “In spec…” after each set point.
3.8 TEST: RESTORE PREVIOUS CALIBRATION
To restore the previous calibration data, select this option. If the .CFG file for the molbox exists,
the previous value in it is used to update the analog circuit’s slope and offset values. If the file does not
exist, the file is created. An example .CFG file is included (see Section 5.4).
