3.8 Calibration
This menu is used to Calibrate the XMT1000 meter to another flow rate reference. Use steps as in section “Log-in and
Primary Pages” to navigate to the Calibration page.
Note:
Use either [Meter Factor] or [K-Table], do not use both at the same time.
1. Scroll and highlight [Meter Factor] and press [ENTER]. Meter Factor is a single multiplier that is applied to the
Composite Velocity measurement. The default value is 1.0 and if a single factor would suffice to bring the velocity
range measured towards another flow rate reference, this option is used. If a single factor is insufficient to cover
the flow velocity range or viscosity range use K-Table option.
2. If using [Meter Factor], skip the following steps, otherwise Scroll and highlight [Calibration Mode] and press
[ENTER]. The meter supports Gate(Totalizer) or Frequency Output Calibration methods.
a.
If Gate(Totalizer) is chosen, connect the Gate inputs to E1 and E2 test points found on the bottom left front side of
the main PCB once the front cover is removed.
b. If Frequency Output is used for calibration, set the [Measurement Type], its corresponding [Base Value], [Full
Value], and respective [Base Frequency], [Full Frequency]. Set a [Test Frequency] value to test the Frequency
Output connection before starting Calibration.
3. Scroll and highlight [Calibration Type] and press [ENTER]. The calibration type can be set to either Velocity or
Reynolds number. Depending on the selection the K-Table points will be updated to accept Velocity or Reynolds
number entries.
4. Scroll and highlight [Reset K-Table] and press [ENTER]. Select the table to reset. You can choose to reset all
tables, or composite K-Table or any specific channel K-Table.
5. Scroll and highlight [K-Table Selection] and press [ENTER]. The default option is Off. For “as found”
calibration leave the [K-Table Selection] as OFF. After completion of the “as found” calibration and
identifying the K-Factor values for each calibration point, select [Composite] table or [Channel] table option.
6. Scroll and highlight [No. of Points] and press [ENTER]. Enter the number of points to enter in the K-Table.
7. Scroll and highlight [K-Table] and press [ENTER]. Select each point and update the [Velocity] or
[Reynolds Number] and its corresponding [K-Factor]. These points define a calibration curve for the XMT1000.
Note:
[K-Table] Velocity or Reynolds number (Point #1 to Point #20) should be entered in ascending order for the
meter to function correctly.
