Calibration
The Hydraulic Analyzer comes calibrated from the factory, but it may be necessary for the operator to reset zero for
the pressure and
fl
ow rate sensors occasionally. Calibration parameters are stored within the electronic interface and
not the PC software. The software application automatically reads the calibration parameters from the device when it’s
launched. Therefore, owners of multiple units can use the same PC without worrying about calibration
fi
les.
To Reset Zero for the Pressure Transducer:
1. Select
Tools – Calibration
from the main menu.

2. Select
the
Pressure
or
Flow
radio button at the top of the calibration screen.
3. Make sure the pressure/
fl
ow of the Hydraulic Analyzer is at zero and press the
Read
button.
4. If the Calibrated Value reading under the Units column is not around zero, press the
Set Zero
button. This will
recalibrate the sensor's zero output and write the value to the Hydraulic Analyzer.
To Reset Factory Calibration Defaults:
Press the
Restore Factory Settings
button.
