Datalogger allows various working data to be captured based on several different triggers. To
use this interface, a serial input device (computer or printer) is used to capture the data from
the
IT400 . Refer to the menu section of the manual to see the data that can be captured and
what triggers are available. Each line of data is terminated by a CR+LF combination (0x0D
and 0x0A). There are two data format outputs available, DB and non-DB:
DB Format: The DB format lists the enabled data in the following order: Time, Total, Rate,
Grand Total, Temperature, K-Factor, and Warnings. Units are the same as displayed on the
LCD. The time listed is the “UNIX” time or the number of seconds from the UNIX Epoch time
(Jan 1, 1970, 0:00:00 GMT). No Daylight Savings Time (DST) or time zone adjustment is
made. Example:
2147498935, 1073, 919.532, 37211, 32.2, 58.71818, 0
2147498937, 1104, 919.687, 37242, 32.2, 58.71818, 0
2147498939, 1135, 919.506, 37273, 32.2, 58.71818, 0
2147498941, 1165, 919.557, 37303, 32.2, 58.71818, 0
2147498943, 1196, 919.609, 37334, 32.2, 58.71818, 0
2147498945, 1227, 919.385, 37365, 32.0, 58.72917, 0
Non-DB Format:
The non-DB format lists the enabled data in the same order as in the DB
format, but will be listed one item per line. In addition, this format shows the engineering units
of each value. The date/time is adjusted for local time zone as set in the menu. DST is not
included as this would allow duplicate time stamps. Example:
Date/Time: Mon Jan 18 2038 13:14:54 GMT-5:00:00
Total: 98 G
Grand Total: 36235 G
Temperature: 32.0F
K-Factor: 58.72917 P/G
Warnings: 0:

Real-time clock maintains the current date and time for use with the datalogger. Each
datalog event is preceded with the current date and time. Time is calculated by maintaining
the number of seconds since the UNIX Epoch time (Jan 1, 1970, 0:00:00 GMT). The real-time
clock does not increment unless the
IT400 is powered (either by DC-in, battery, or 4-20mA).
When the battery is replaced, the internal clock will be slow by the amount of time between the
time the menu is entered (just prior to removing the battery) and the time the
IT400 is again
powered (after the battery replacement). The real-time clock can be set in the menu system
and is only available when the datalogger option is purchased.
Inputs
The IT400 has four inputs: RS-232 interface, user interface, temperature, and input signal.
•
RS-232 interface is described above.
•
User interface is described above.
•
Temperature input is a standard 2-wire platinum RTD temperature probe (0.385 TCR). The
temperature probe is typically mounted within a few inches downstream of the attached
flowmeter. The temperature input will increase the drain rate on the battery when the
IT400 is
battery powered. The temperature input is ignored if the temperature compensator is disabled.
