Scaling and Calibration
It is very important to read the following information, before proceeding
to program the controller:
• There is
no need to recalibrate
the controller when first received
from the factory.
• All inputs are factory calibrated. The calibration equipment used is
certified to NIST standards.
• Use the
Scale
menu to enter the scaling without a signal source.
• Use the
Calibrate
menu to apply a signal from a calibrator or a
flowmeter for the scaling.
Setting the Input Signal (Input)
PD6210:
Enter the Input menu to set up the controller to display current
(mA) or voltage (volt) inputs.
The current input is capable of accepting any signal from 0 to 20 mA.
Select current input to accept 0-20 mA or 4-20 mA signals.
The voltage input is capable of accepting any signal from -10 to +10 VDC.
Select voltage input to accept 0-5, 1-5, 0-10, or
±10 VDC signals.
PD6310:
There is a switch, located to the right of the input connector,
which must be configured according to the input level and type. Jumper
J4 located inside the controller, behind the input signal connector, is
used to select the excitation voltage (24 V*, 10 V or 5 V) which is
supplied to the P+ and P- wiring terminals.
The controller may be calibrated using the K-Factor function. Most
flowmeter manufacturers provide this information with the device. Enter
the K-Factor (Factor) menu and select the decimal point with highest
resolution possible and program the K-factor value (i.e. pulses/gal). The
controller will automatically calculate the flow rate using the K-factor and
the time base selected.
*Default setting
Setting the Totalizer and Batching Features (total)
After the input type is entered, set the total parameter to “Yes” to
enable batch control (this is set by default). If the total features are
disabled, most batching features and functions are hidden from the
menus.
