Automatic Zero/Span Check | Teledyne 300M instruction

Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A

3.4 Automatic Zero/Span Check

Automatic zero/span checking (Z/S check) must be enabled in the setup mode. The Teledyne API Model 300M Carbon Monoxide Analyzer with Zero/Span Valves option offers capability to check the zero and span point automatically on a timed basis, or through remote RS-232 operation (see Section 3.7).

Under the SETUP-ACALmenu, there are three separate auto-sequences called SEQ1, SEQ2, and SEQ3. Under each SEQ, there are four setup parameters that affect zero/span checking: the mode, the starting date of the check, the time of day for check, the number of delay days, time delay, the duration of the check, the range to check and whether to calibrate as well as check the range. These are described individually below. Use the PREV and NEXT buttons to scroll through the three sequences. The mode for each sequence is displayed. To change the mode for any of the sequences, scroll to the desired sequence and press the MODE button. Use the PREV and NEXT buttons to select one of the modes shown below and press ENTR.

Mode:

1.DISABLED (Sequence is disabled)

2.ZERO

3.SPAN

4.ZERO-SPAN

To change the setup parameters for a sequence, press the SET button. Pressing the <SET and SET> buttons allows you to scroll through the setup parameters and edit them by pressing the EDIT button. The function of each setup parameter is described below:

Timer Enabled: When set to ON, the sequence will be executed based on the internal timer, as specified in the following parameters. When set to OFF the sequence will be executed only upon an external (RS-232) command.

Starting Date: The starting date for the sequence is entered in the format of MM/DD/YY, where

MMis the month, DD is the date, and YY is the year. Enter starting date and press ENTR or EXIT to leave the date unchanged.

Starting Time: To set the time of day for the sequence, enter in the format HH:MM, where HH is the hour in 24-hour format (i.e. hours range from 00 to 23) and MM is the minute (00 - 59). Enter the time of day for calibration check and then press ENTR to accept the new time or EXIT to leave the time unchanged.
