Description Volume and discharge can be inconveniently large numbers.
For example, the SDI-12 protocol does not permit more than
seven digits in a single number. The scale factors shifts the
decimal point up to six places to the left. This effectively pro-
vides more units than the IU command alone does. For exam-
ple, suppose the volume is 12345678.9 cubic feet. If the IT
command is set to 3, this would become 12345.67 kilo cubic
feet.
The IT command depends on the IU command (see “IU - Out-
put Units,” page 69). The IT command only changes the vol-
ume if IU has set the volume unit to:
1 = Cubic meters
2 = Cubic ft
3 = Gallons
The discharge exponent is applied for all discharge units.
NOTE. In order to be able to correctly interpret output at a later time, you
should make careful records of the units and scale factors that you
selected above.
IZ - Zero Volume Accumulator
Purpose Resets or displays the cumulative volume.
Format IZ ZeRo (Reset to zero)
IZ ? (Display cumulative volume)
Range N/A
Default N/A
Recommended Setting. Use as needed. Reset using WinHADCP.
Description IZ ZeRo resets the cumulative volume to zero. This command
is case sensitive and must be entered exactly as shown. Use
“IZ ?” to display the cumulative volume in cubic meters.
Some instruments cannot handle values larger than one mil-
lion. For this reason, the cumulative volume is split into two
numbers. The first number is the millions part of the volume.
The second part is the rest of the volumn.
For example a volume of 12,345,678.90 cubic meters would
be reported as the following:
iz 12, 345678.90 ------ -----. zeRo Volume Accumulator
