I.0 INTRODUCTION

1.1 GENERAL DESCRIPTION

The Cleveland Controls Model 6650 Digital Manometer provides
accurate measurement of differential pressure up to 10" wc. Pressure
readings are digitally displayed on the 3-½ digit LCD display, in two
common engineering units (Inches H
air sample ports located on the front of the instrument accept ¼"
ID flexible tubing. Included with the manometer is a 10-foot (10')
length of flexible vinyl tubing, to be cut following guidelines in this
manual. The manometer is compatible with air and other dry, clean,
non-corrosive gases that will not attack polyester, vinyl, silicone, or
silicone-based adhesives.
In addition, an electrical continuity test circuit is provided for
convenient testing and calibration of pressure sensing switches. NO,
NC, and COM continuity test connections, plus red and green LED
indicators, are located on the front panel. A 3-prong continuity test
cord, six-feet (6') long is included with the manometer.
An analog output signal (0-1 VDC) is provided to permit remote
pressure recording or monitoring. Analog output terminals are located
on the rear panel.
The manometer is powered by a internal rechargeable battery
pack. It can also be connected to an AC line via the power receptacle
located on the rear panel and the provided AC cord.
The Model 6650 Digital Manometer is factory calibrated and
requires no routine maintenance.
