Model
Choose the Ruskin Model that is piped to the DPT-IQ. (Or CCUV if not listed)
2
Response The Ruskin DPT-IQ enables you to set the Response Time from 1 – 20 seconds with 1 second increments.
Time
Increasing the Response Time can reduce the influence of air turbulence.
3
Mode
Use jumpers to complete, as described in Step 3 above.
4
V output The Ruskin DPT-IQ enables you to set the Velocity or Volume Output Maximum, to improve resolution of the flow reading,
Max
by limiting the range. NOTE: Output Units can be different from Display Units.
CFM
50 Min to 100,000 Max - 1 CFM increments
l/s
25 Min to 50,000 Max - 1 l/s increments
m/s
1 Min to 100 Max - 1 m/s increments
FPM
2,000 Min to 20,000 Max - 10 FPM increments
m/min
60 Min to 6000 Max - 1 m/min increments
m3/s
0.025 Min to 50 Max - 0.001 increments
EXAMPLE: The DPT-IQ has an effective range of 50 – 100,000 CFM. If Flow Volume readings are expected below 12,000
CFM, adjust the V Output Maximum to 12,000 CFM, to improve resolution. The DPT-IQ can have the V Output Maximum
set between 50 – 100,000 CFM, to improve resolution.
5
P output
Set the Pressure Output Maximum, to improve resolution of the Pressure reading,
Max
by limiting the range. NOTE: Output Units can be different from Display Units.
inwc
0.10 inwc Min to 4.0 inwc Max - 0.01 inwc increments
Pa
100Pa Min to 1000Pa Max - 50Pa increments
EXAMPLE: The DPT-IQ has a capable range of 0 – 4.0 inwc. If pressure readings are expected below 1.00 inwc, adjust
the Pressure Output Maximum to 1.00 inwc, to improve resolution. The DPT-IQ can have the Pressure Output Maximum
set between 0.1 – 4.0 inwc, to improve resolution.
6 line 1 Unit Choose which SI unit (inwc, FPM, CFM) or UI unit (m3/s, Pa, m/min. m/s, l/s) you will use.
7 line 2 Unit Choose which SI unit (inwc, FPM, CFM) or UI unit (m3/s, Pa, m/min. m/s, l/s) you will use.

Gain The GAIN feature is designed to allow modification to the reported output. The number shown is a multiplier. Increase
the reported output by increasing the GAIN number above 1.000. (To increase reported output by 5%, adjust number to
1.050. Decrease the reported output by decreasing the GAIN number to less than 1.000. (To decrease reported output by
5%, adjust number to 0.950. The range is from 0.200 to 5.000 with 0.001 increments.

area Area is computed when you enter duct height and width for rectangular units, and diameter for round units. The computed
value can be over-ridden if you enter an area (in square feet) in this selection.

* CCUV (Custom Configurable Universal Values) allows for Ka values and exponent values to match any device not listed in the Model column.
Default value is Ka = 4005 and exponent 1/m = 0.5
