C. User Adjusted Gain
The user may adjust the calibration gain if using different uids, temperatures or variables from the pre-
programmed calibrations.
1) Set up the tubing calibration system with the desired parameters.
2) Choose the calibration setting which most closely matches the system setting.
3) Nullify the zero offset as described in “Flowsensor Zero Offset” on page 11.
4) Preform a multi-point calibration to create a calibration curve and determine the % correction required.
Flowsensor calibration instructions are found in RL-34-tn.
5) [Select] “User Adj Gain” to alter the factory calibration by percent (%) according to the results from
the previously performed calibration. NOTE: This new calibration gain will be stored in the Flowsensors
EPROM and becomes the default calibration until reset to factory default of 100%. Calibration selections
which have user adjusted gains have a % symbol next to them in the “Sensor Controls” menu and a *
star indicating that they have been adjusted.
D. Calibrating a Data Acquisition System
The calibration reference signals are located in the [Menu] (see ”Program Menu” on page 13 for Menu
setup diagram). [Select] “Meter Controls” then [Scroll] to “Calibrate Scale” and press [Select]. The “0
Volt Scale” and “1 Volt Scale” settings are provided to generate 0 and 1 Volt reference scale signals for
calibrating a data acquisition system.
1) Connect the data acquisition system to either the front or rear analog outputs.
2) Follow the data acquisition provider instructions for a 2-point calibration.
3) For reference point “zero” (0 volts), [Select] “0 Volt Scale” and record the output voltage. NOTE: A star
(*) appear when the signal is active. NOTE: In the “Calibrate Scale” menu either “0 Volt Scale” or “1 Volt
Scale” is always active. Exiting the menu deactivates the calibration signal.
4) For reference point “1 volt”, [Scroll] to “1 Volt Scale” and press [Select] and record the voltage. The
value of the 1 volt reference signal is the Sensor scale factor that is displayed on the LED display of the
Module. NOTE: The Flow Module can read up to ve times the scale factor value.
5) If the scale is changed (Standard Flow vs. 1/4 Scale Flow) during the experiment, the 1 volt reference scale
value in the data acquisition system must be reset. The voltage range for the Flow Module remains the
same, but the scale factor changes. Repeat the calibration sequence above whenever the ow range
setting has been changed.
