Calibration
A "Zero Adjust" calibration can be performed on this
logger. SW400 calibration software is required.
Note: It is strongly recommended that a higher
accuracy NIST'd instrument be used as the standard.
For more accurate calibration, return the instrument
to Dickson for calibration in our A2LA Certified lab.
Contact Customer Service for a Return Authorization
Number before returning for calibration.

Logger Settings
When changing logger settings (sample interval, sub
10 second interval and stop/wrap) the logger will
automatically clear all stored data.
Fahrenheit/Celsius
• The data logger is defaulted to log data in
"fahrenheit". To change graph view in DicksonWare
from "fahrenheit" to "celsius", go to "File/
Preferences" to change temperature selection.
• To change display setting, hold down the Alarm
button for about 5 seconds. The display will toggle
between "F" and "C".
Troubleshooting
Display Reads PROB
Models SM320/325 will display "Prob" if the
thermocouple is not connected.
Logger will not communicate via Serial COM port
connection
• Make sure you are using version 11 or higher of
DicksonWare
• Verify that the correct COM port is selected. From
the main Dicksonware screen, click on Logger, then
Communication. A black dot will appear next to the
selected COM port. You may need to select a different
COM port. Should you get an error message stating
that "Device Is Already Open", this could mean that
you do not have the proper COM port selected, but
another device, or it's software, has it allocated. Palm

pilots, for example, will cause this problem, which in
this case, the port is not actually "available" and you
may have to disable that device.
• You may need to relocate the download cable to
another serial port on the back of the PC and possibly
try changing the COM port again in DicksonWare™.
• If communication has not been established with the
previous steps, you may need to remove the batteries
and then try all COM port and cable combinations
again.
• If possible, try another PC
• Make sure that "USB" is not checked in File/
Preferences/Communications.
Logger will not communicate via USB port connection
• Make sure that "USB" is selected under File/
Preferences/Communications.
• Unplug USB cable and plug back in.
• Remove all power to the logger. (This will not cause
the unit to lose any data within the logger, but
you will have to start the unit logging again using
DicksonWare™.) Unplug the USB cable, power the
logger back on, then reconnect the USB cable.
• If the logger was used in a moist or humid environment
condensation may have formed on the unit. Place unit
in a warm dry environment for 24 hours. Clear the
memory and try again. These loggers are designed
for use in a non-condensing environment. If the
environment creates condensation, try placing the
unit (temperature only models) in a small sealed
plastic bag to protect it from condensation.
• If possible, try another PC, and/or another USB port
and/or USB cable.
Err 14 Code Displayed–Will not save data to MMC card
This is a generic fault code. There is something wrong
with the MMC card (full or not formated correctly) or
there is a hardware issue (a bad connector or no card
present - can''t see any card). Try another card (make
sure is is an MMC card not an MMC Plus card), and
that it has been supplied by Dickson. For additional
information on formatting your own MMC card go

• Replace the batteries, they may be low.
• SM420–Unit is reading -400 when the probe is
in an environment that is nowhere close to that
temperature.
