4. PROGRAMMING
The Model IT375 is fully programmable with all parameters being stored in non-volatile memory.
The Program Mode can be entered in one of two ways:
1. By removing the lower cover strip (ie. the dark grey strip along the bottom of the enclosure) and reversing it’s left
– right orientation. This brings a small magnet on the inside of the cover strip in contact with a reed switch inside
the instrument.
2. By removing the front section of the enclosure which contains the main processor board and batteries.
The PROGRAM key is used to step through the program (CAL sequences) and the ACCUM TOTAL and RESET keys
on the front panel are used to change and increment the flashing digits.
Note that only flashing digits can be changed.
Up to eighteen CAL steps are accessible depending on which options are installed. The CAL number is displayed in the
lower right display and the parameter is displayed above it.
Parameters in Program Mode that consist of whole numbers and digits after the decimal point are restricted to a
maximum of 6 digits combined. Therefore, the number of significant digits entered as whole numbers will determine the
number of available digits after the decimal point.
Example:
The entry of 1, 100 and 10,000
000001 in the whole numbers leaves 5 digits available after the decimal point
000100 in the whole numbers leaves 3 digits available after the decimal point
010000 in the whole numbers leaves 1 digit available after the decimal point
