OPERATION

Extended Operation Modes

The measurement capabilities of the MT100 are expanded with the following extended operating modes:
● External Input Flow Adjust (EIA)
● External MT100 Flow Input (EFI)
● External Control Group Switching (EGS)
Use the MT100 Configuration Software application to set up an extended operating mode. The front panel HMI menu cannot be used to
program this feature.
Once the MT100 is set up with an extended operating mode, the mode's initials (EIA, EFI, or EGS) are shown on the front panel HMI
display to show that the mode is active. See Figure 38 below.

External Input Flow Adjust (EIA)
This mode corrects the flow rate of an MT100 flow meter when an external 4-20 mA current is fed into the 4-20 mA input port. Four
polynomial factors are used to determine the correction applied to the flow rate and corresponding 4-20 mA output. The equation that
defines this correction is as follows:
Corrected Flow Rate = Starting Flowrate x [(Factor 1) + (Factor 2 x mA Input) + (Factor 3 x mA Input
Make all necessary connections as shown in the wiring diagram in Figure 39 below.
Start the application. Click USB Connect on the home screen. Select the Configuration branch from the menu tree on the window's left
side. Select the Extended Op. Mode tab. Click Toggle System Mode. Enter user level password 2772 at the prompt. Verify instrument is
in the service state with Setup showing in System Mode field. Click External Input Flow Adjust (EIA) radio button. In the window's Ext.
Input Flow Adjust Setup field enter the four polynomial factors in the text box for Factor1, Factor2, Factor3, and Factor4.
At window bottom click Set System Mode to 'Running' when Send check box. Click Send to Device near check box to send the EIA
programming to the instrument. Observe return to normal operation with Running showing in System Mode field.
