Makeup Latch
A fault condition (caused by an empty pipe or a transient loss of power, etc.) could tempo-
rarily interrupt operation. After recovery from the fault, the meter executes an in-process
makeup to restore operating parameters. During the makeup, the meter sets a Makeup Alarm
flag, which clears upon completion. Therefore, unless you were monitoring the unit continu-
ously, you could miss the fact that an In-process Makeup occurred. The Makeup Alarm Latch
alerts you that the system implemented a Makeup by holding the Makeup Alarm active until
you reset it manually by the simultaneous keystrokes: <Fn>6 (where “n” represents the mea-
surement channel). In addition, if the Datalogger is active with Status Alarms selected, gen-
erating a Datalogger report will reset the Makeup Alarm Latch. This ensures that the Alarm
does not appear on succeeding Datalogger reports. A Makeup Alarm appearing on a subse-
quent report indicates that an In-Process Makeup must have occurred since the last Datalog-
ger report.
To enable or disable the Makeup Latch:
To access the [Makeup Latch] option list press
Move the cursor to select either [On or Off] by pressing
To turn Makeup Latch [On] or [Off] press
2.7.3 CALIBRATE FLOWRATE AND CALIBRATION TABLES
System 1010PVN equipment provides three ways to condition the calibration performance of
its flowrate output: Intrinsic (factory set), Kc, and Calibration Tables 1 through 3. Access to
these calibration options is found in the [Calibrate Flowrate] menu cell and the three [Calib.
Table] menu cells of the Data Span/Set/Cal menu (refer to Data Span/Set/Cal menu on next
page).
The 1010’s intrinsic calibration is excellent as confirmed by numerous laboratory and field
trials under diverse application conditions. Controlotron can confidently say that in any given
application, the majority of conventional flowmeters can not match the system’s measure-
ment range or its linearity.
Intrinsic
When selected, the meter uses no slope adjustment at all. Output data is still zeroed and
corrected for Reynolds number, but no slope adjustment is imposed on the meter’s flow regis-
ter.
Some applications may require an output adjustment to match an official external reference.
The [Calibrate Flowrate] menu allows you to select a calibration mode. The right-hand col-
umn shows the active calibration mode. You can select Intrinsic (factory) and Kc (Slope Cor-
rection) Calibration. Selecting either of the external calibration modes will not eliminate the
Intrinsic (factory) calibration. You can use this menu cell to switch between Intrinsic and Kc
at any time.
