Section 1 - Introduction and General Information
This instrument is a microprocessor based circular chart recorder capable of measuring, displaying, and recording
from a variety of inputs. Applications include temperature, level, pressure, flow, and others. The instrument can
be specified as either a one, two, three, or four pen model.
The standard process sensor inputs (up to 8 total inputs) are user configurable to directly connect to and convert
thermocouple, RTD, millivolt, volt, milliamp or contact closure inputs. Thermocouple and RTD linearization, as
well as thermocouple cold junction compensation, are performed automatically. Up to four individually isolated 24
VDC regulated transmitter power supplies are available for transmitter inputs, each providing up to 25 mADC.
Using the optional math capability, mass flow, BTUs, relative humidity, and other derived variables can be calcu-
lated, as well as simple math functions performed and custom curve conversions. Optional totalization is avail-
able for input values or derived variables. Any recorder value can be treated as a process value, to provide
alarming and special display capability.
Up to 4 variables can be recorded as analog trend lines on chart sizes of 10, 11, or 12 inches in diameter. The
trend lines can be the result of instantaneous values, connecting the values, drag pen, average values, or con-
necting the average values. The trend lines can be scaled and positioned on the chart in zones. Trend scales,
units, and a trend tag can be printed in the same color as time lines.
Dates, times, batch numbers, operator IDs, process values, scales and alarm messages can all be printed on the
chart in color.
Definitions for a large number of "Terms and Concepts" described in this manual are included in Appendix C.
1.1 UNPACKING
Remove the instrument and pen cartridge assembly from the shipping container and inspect for any damage due
to shipment. If any damage is noticed due to transit, report and file a claim with the carrier. Write the model
number and serial number in spaces provided on Page 1-3 of this manual for future reference. The model
number and serial number are found on the label on the case, viewed when platen is open.
