Programming the Meter (
prog
)
It is very important to read the following information, before proceeding to program the meter:
•
The meter is factory calibrated prior to shipment to read in milliamps and volts depending on the input
selection. The calibration equipment is traceable to NIST standards.
•
Use the Scale menu to scale the process input (e.g. 4-20 mA). A calibrated signal source is not
needed to scale the meter.
•
Use the Calibrate menu to apply a signal from a calibrator or a flowmeter.
•
The DPM-500 is a single input meter with dual-scale capability.
The Program menu contains the Scale and the Calibrate menus.
Note: The Scale and Calibrate functions are exclusive of each other. The meter uses the last function
programmed. Only one of these methods can be employed at a time. The Scale and Calibrate functions
can use up to 32 points (default is 2). The number of points should be set in the Advanced menu under
the Multi-Point Linearization (
Linear
) menu selection prior to scaling and calibration of the meter, see
page 41 for details.
If the dual-scale level feature is selected in the Setup menu, the Scale 1 and Scale 2 menus are enabled
for PV1 & PV2 respectively.
The process input may be calibrated or scaled to any display value within the range of the meter.
Program Menu for Single Scale Process
Program Menu for Dual-Scale Level Applications
Additional parameters, not needed for most applications, are programmed in the Advanced Features
menu; see Advanced Features Menu , page 38.
Multi-Point Calibration & Scaling
The meter is set up at the factory for 2-point linear calibration. The number of points for multi-point
calibration/scaling is set up in the
Advanced Features menu. Up to 32 linearization points may be
selected for PV1 and up to 8 linearization points may be selected for PV2. See page 41 for details.
