9.5 Calibration Menu
The calibration menu provides menus for calibration of the following:
• zeroing the flow meter
• temperature
• density
• mass
• analog outputs
The pulse output only requires configuration. For pulse output configuration see
Section 9.6.6.
9.5.1. Zero Calibration
NOTE: Correctly zeroing the mass flow meter is critical for accurate mass
flow measurement.
The Datamate 2200 transmitter allows the user to review and modify the electronic
zero, transducer zero and the system zero.
Automatic Zero Procedure - See Section 7.4.
Manual Zero Procedure
To complete a Manual Zero, use the following menu and description chart to
perform the following:
• Set the SYSTEM ZERO to “0” DEG
• EXIT out to the MAIN MENU
• From the MAIN MEASUREMENT DISPLAY, press ENTER until PHAS DEG is
displayed on the LCD
• Under no flow conditions record the maximum PHAS DEG value
• Enter the recorded value into the SYSTEM ZERO
The procedure for zeroing the flow meter is as follows:
Menu or Display Description
Program
This menu allow the user to review and modify the Electronic, Transducer
2. Zero
and System zeroes.
Choices from this menu are Electronics Zero, Transducer Zero , System
Zero, and Exit.
The Transducer zero is the phase measurement offset of the transducer
when there is on flow. The transducer zero cannot be measured directly and
is defined as the difference between the System zero and the Electronic zero.
Zero
This menu allows the user to review and modify the Electronic zero of the
1. Electronic Zero
Datamate 2200.
The electronic zero is the zero offset contribution due to the electronics and is
determined by zeroing the electronics with the sensor inputs shorted together.
Choices from this menu are Elec. Zero Params, Zero Electronics, and Exit.
