To use Program #0
Program #0 is used to send the previous command. Resending the last
command is useful if it involved a number of keystrokes. Program #0
will resend all of the commands except for the following:
• ZERO
•CAL
• ADDRESS
• INITIAL CAL OR INITIAL CALIBRATION
• SET TIME on the Calibrator
• SET DATE on the Calibrator
To resend any command except for those listed above:
1. Press the PROGRAM key.
2. Press the "0" key. (This is the number zero key, not the key
labeled ZERO.)
3. Aim the Controller at the Ultima Gas Monitor and press ENTER.
If the last command is one of the three listed above, it will not send that
command; instead, the Controller will send the preceding command.
