DSGH Installation and Operation Guide 51
Calibration
During the standardization procedure, the system displays:
• A default value for the standardization condition
• A prompt to enter the actual process value of the standardization
condition
Standardization reminder
If you enable the standardization due alarm, the gauge produces an alarm
when standardization is due. The standardize interval is programmed in
Setup | Cal Parameters.
You can perform a standardization using any of the following:
•Process
• Water (or other repeatable fluid)
• Absorber plates
Standardization on water
Standardization on water is the best choice if water is readily obtainable.
For example, if the process is water based or if the process is slurry with
water as the carrier.
Advantages: If the source of water is of consistent purity (for example, city
vs. pond), standardization on water is highly accurate. Water is a good
choice if the density of the process is around 1.0SpG because
standardization on water would be within the process span. This ensures
high accuracy at the point on the calibration curve.
Disadvantages: You must be able to empty and fill the process pipe with a
consistent source of water.
Note: This method requires you to select Default Value and enter the
Standardize Default Value on the SetUp | Cal Parameters tab.
