Service Manual
Name
Test hoses, 3 m (10 ft)
Interconnect hose, 1.8 m (6 ft)
Supply hose, 1.8 m (6 ft)
Notes:
1. IQC70 is a Fluke Calibration interlocking quick connection nominally rated to 70 MPa (10,000 psi).
2. Hose limited to 3,000 psi due to miniature QC used to connect to the fitting on the regulator.

Notes:
1. Measurement uncertainty is defined as the maximum deviation from the indicated value of measured pressure for 1 year
after alignment including hysteresis, linearity, repeatability, stability, temperature, humidity effects, and calibration reference
standard measurement uncertainty. Expression of uncertainty uses a coverage factor of 2 and conforms with the
recommendations of the ISO Guide to the Expression of Uncertainty in Measurement.
2. Negative gauge and vacuum pressure values assume the ambient atmospheric pressure is approximately 101 kPa
(14.7 psi) absolute.

Pressure Control Specifications

Control Precision .................................................. Greater of ± 0.025 % of reading or ± 25 Pa (0.0036 psi).
