DICKSON
Getting Started
This recorder comes with 1 AA battery installed.
When installing recorders (1/4” male NPT pressure connection) always tighten the fitting instead of
twisting the instrument case. Use a 5/8” wrench. We recommend wrapping the pressure fitting with
pipe tape before installing to prevent leaks. Dickson does not recommend using pipe dope as it may
clog the capillary.
Place a new chart on recorder
Set time by inserting a coin into chart hub and turning clockwise until the current hour is referenced to
the time index clip. (Time index clip is directly to the right and below the pen tip).
Remove protective pen cap.
Turn the instrument on. The ON/OFF switch is located inside the door on the dial plate. (PR4-10 does
not include on/off switch)
Pen Replacement
Slide the used pen cartridge off and slide the new one on. Typical pen life is one year.
Battery Replacement
The battery compartment is located inside the door, in the lower left section of the dial plate. The recorder
uses a standard “AA” battery. Typical battery life is one year.
Turn the battery cover counter clockwise with a coin to unscrew the it.
Place the new battery in the holder with the positive end facing out toward the battery cover.
Replace the cover and turn clockwise to tighten.

DICKSON
Calibration Services - New Units
N100 - NIST Traceable Calibration 1-Point: Includes documentation to one Dickson pre-selected
point on new units only.
N300 - NIST Traceable Calibration 3-Point: Includes documentation of three Dickson pre-
selected points (a high, medium, and low) on new units only.
The Importance and Benefits of Regular Calibrations
Once you begin to use your precision Dickson instrumentation, regular calibrations are necessary to ensure
accurate readings.
The following Calibration Services are available:
N150 - NIST Traceable Calibration 1-Point: Includes documentation to one Dickson pre-selected
point after re-calibration.
N350 - NIST Traceable Calibration 3-Point: Includes documentation of three Dickson pre-
selected points (a high, medium, and low) after re-calibration.
Why should I recalibrate my instrumentation?
Over time dirt, dust and normal handling can throw your precision instrumentation out of calibration. Regu-
lar calibrations ensure that you receive the most accurate readings possible.
How often should I recalibrate my instrumentation?
Depending on the environment your instrument is used in and how often it is handled you will want to
recalibrate your instrument every 6 to 12 months. Instruments in environments where there are extreme tem-
peratures, wide temperature ranges, humidity or pressure variations, high condensation, dirt, dust and other
debris will require calibration at least every 6 months. Instruments that are frequently moved or in locations
with heavy machinery that cause vibrations should also be calibrated at least every 6 months.
Why should I return my instrument to Dickson for calibration?
Dickson calibrates your instrument at the factory using proprietary production/calibration software that
guarantees proper calibration.
Our Capabilities
Dickson is the first manufacturer of humidity and temperature instrumentation to receive A2LA accredita-
tion. We are also NIST Traceable; our procedures conform to MIS-STD-45662A, ANSI/NCSL 2540-1-1994,
ISO/IEC Guide 25 and ISO10012. We are experts in the manufacture and calibration of humidity and tem-
perature instruments.
Fast Service: Our turnaround time is 3 days or less so you receive not only expert service but fast
service as well.
Easy: We make it easy for you! No phone calls for Return Authorization Numbers are required. We
remind you when your instrument is due for calibration. You simply send in the completed Calibration
Order Form with your unit for calibration with freight prepaid to Dickson.
Calibration
Periodically check accuracy with a test gauge. If pen adjustment is required, use the adjusting screw located
inside the door on the upper left corner of the dial plate. Check two points on the scale when adjusting the
pen to make sure recorder calibration is maintained.
Note: When no signal (no pressure) is being applied to the recorder, the pen may not rest exactly on the
zero chart line. It is possible for the allowable 2% of scale error to occur at zero, while upscale readings are
increasingly more accurate.
