1. INTRODUCTION This series of panel instruments is a versatile, cost effective solution to a wide variety of monitoring and control applications. These instruments are easily set to produce an accurate display of temperature, pressure, flow, weight, voltage or current. Front panel push-button or RS-232/RS-485 setup allows the user to customize the unit for a specific application. Digital scaling of zero and span provides direct readout in engineering units.
2. RECEIVING AND UNPACKING Your meter was carefully tested and inspected prior to shipment. Should the meter be damaged in shipment, notify the freight carrier immediately. In the event the meter is not configured as ordered or the unit is inoperable, return the unit to the place of purchase for repair or replacement. Please include a detailed description of the problem. 3.
4. 4.1 CONNECTOR WIRING INFORMATION CONNECTOR LOCATION The connectors are the screw terminals that plug into the mating jack mounted on the printed circuit board. P3 is either a 6 conductor phone plug for RS-232 and RS-485 or a 30 pin, mass termination, edge connector for parallel BCD. J1 1 1 J5 J3 J2 1 6 1 J4 6 6 6 4.

6. PANEL MOUNTING Ensure the O-ring is in place. Turn the two mounting screws counterclockwise until the space between the mounting pawl and the bezel is greater than the panel thickness. Insert the meter in the panel cutout. Turn the mounting screws clockwise until the meter is securely mounted in the panel. Do not overtighten the mounting screws. 48mm (1.89in) 96mm (3.78in) 5mm (0.197in) J1 J2 J3 J4 FRONT VIEW REAR VIEW TOP VIEW SIDE VIEW J5 Mounting Pawl 102mm (4.

Logical 1 - The displayed value is equal to the signal input minus the tare value. Peak Display Logical 0 - The peak value of the input signal is displayed. Logical 1 - The present value of the input signal is displayed. Hold Logical 0 - The meter display and outputs are held at the last reading.
24. CALIBRATION All ranges of the meter have been digitally calibrated at the factory prior to shipment. The calibration equipment is certified to NIST standards. Calibration constants are stored in nonvolatile memory in EEPROM on the signal conditioner. This eliminates much of the analog circuitry that causes drift and provides superior long term accuracy and stability.
