Using the Smart Interface Software Advanced Features
Select the Advanced Options button to:
Save Variables to Disk. This routine allows you to save the complete
flow meter configuration to disk. As a safety measure, you should
perform this routine to create a back up file of the existing configu-
ration before making any changes.
Read Variables From Disk. This routine allows you to upload the
variables from a data file into the currently connected flow meter.
(You should perform “Save Variables To Disk” function before
over-writing the system configuration with new information.)
Voltage Zero & Span Adjust and Current Zero & Span Adjust can be
used to validate system operation and calibrate the digital to analog
signals on the Smart electronics device. Additionally, zero and span
adjustments can compensate for resistance in long signal cables con-
nected to your data collection or indicating system. Adjusting zero
and/or span affects meter calibration and affects both ranges. You
must use a certified digital voltmeter (DVM) to adjust zero and span–
the DVM acts as a standard. Please note that when adjusting zero the
voltage signal will be driven to 0 VDC and when adjusting span the
voltage signal will be driven to 5 VDC (or 10 VDC if equipped with
the 0-10 V output option), or when adjusting zero the current signal
will be driven to 4 mA and when adjusting span the current signal
will be driven to 20 mA.
