INTRODUCTION
The DX600 circular display board provides a calibration facility
for the TX600 Circular Transmitter Board and also provides a
loop monitor display. The DX600 is mounted directly above the
TX600 and is connected to it by a vertical 8-way double inter-
PCB connector. The whole assembly may be installed in an
explosion-proof enclosure. Refer also to the TX600 data sheet.
Following these specifications, the full calibration procedure is
