Why should I calibrate?
All instruments lose accuracy over time due to normal usage and the environmental conditions to which they are exposed.
How often should I calibrate?
For most applications, the recommended calibration interval is every twelve months.
What is NIST Calibration
NIST stands for the National Institute for Standards and Technology. This organization is responsible for maintaining the master for different measurements, such as the standard "foot", standard, "second", or standard "pound". NIST also maintains the standard for temperature, humidity and pressure.
NIST Traceable means that the measuring standard can be traced directly back to the master standard maintained by the NIST organization.
NIST-Traceable does not tell you the measurement accuracy of a metrologty service in any detail. Only metrology services that can document their ISO 17025 standard provided data on their best measurement uncertainty.

See message "Network Fields Failed to Update" when setting up email in DicksonWare Secure with Email.(TM725)Check your software version. Versions prior to 11.4 contained a bug that caused the email communication to fail if the email address was over a certain length. Contact customer service for an upgrade.
Why does the temp/Rh show a -414F(-247.78C) and 0 Rh reading? (TM325/TM725 only)
- This is normal when the probe is not connected at the time a sample is taken.
Why won't my TM325/725 communicate if my probe isn't connected?The TM325/725 will only communicate if the probe is connected.
How do you change the display between F and C?
- Press and hold the alarm button for 5 seconds.
Problems communicating with the Flash Card?
Flash cards not purchased through Dickson should be formatted. If formatted after experiencing issues the unit will have to come back to be reset.
1. Insert flash card into card reader
2. Go to My Computer and right click on the drive letter that corresponds with the card
3. A menu will appear. Choose the format option
4. Another window will appear
5. Under the "File System" heading, drop down the menu and choose the "FAT32" option
6. Then click on the start at the bottom of the window
This will format the card in the correct manner for use with the unit.
What do the following error codes mean when using a flash memory card?
Err 1 - No memory card
Err 2 - Memory card locked or protected
Err 3 - Wrong size file (too big) or no data to log yet
Err 5 - Trouble writing file to card
Err 14 - This is a generic fault code. There is something wrong with the 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.
Err 16 - Trouble accessing card
Err 23 - Memory card requires reformatting
Err 7 or 66 - Memory card full
Err 49 - Unknown error
Why does my logger stop logging when I use the Flash Memory Card?
The Flash Memory Download Feature was designed to work with standard MMC cards. MMC Plus cards can cause the unit to stop logging when used to download data. If you think the unit stops logging when the Flash Memory Download Feature is used, you might be using a MMC Plus card. We recommend using Dickson Flash Memory Cards.
Why doesn't my display min/max match my min/max alarm settings?The min/max on the display is not the min/max alarm settings. The min/max on the display shows the temperature or temp/Rh min/max only.
Why is my download to a flash memory card taking longer than usual?The more files stored on the card, the slower the download. It's a good idea to clear the memory card occasionally.
Why won't the logger communicate using a serial connection?
Verify that you have the correct version of DicksonWare software installed on your PC. Version 8.0 for all units except the Net Loggers which require Version 9.0
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 have the proper COM port selected, but another device, or its software, has it allocated. Palm pilots, for example, will cause this problem, in which 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 the USB is unplugged, and that USB is NOT checked in File > Preferences > Serial.
Why won't the unit power up or why is the display frozen?
Try removing the batteries and ac power (if applicable) for a few moments, (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).
Batteries may be too low, replace batteries.
Unplug USB cable and plug back in.
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 hrs. Clear 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.
Does each logger need it's own IP address?
Yes, each unit has to be assigned it's own IP address.
How many email addresses can be setup to receive email alerts?
2 email addresses can be setup to receive alerts.
Why do I get the error message "IP Address Has Not Changed" when changing my IP address?
A/C power must be used when changing the IP address.
Why won't my communicate after setting the IP address using USB?
When the IP address is set using USB and the logger is then connected to the network, the logger will not be detected until all power (AC and battery) is removed and the unit is then powered on again.
Why won't the logger communicate using an Ethernet connection?
Make sure the unit is set up first using USB or serial.
My unit will not send emails.
The netlogger uses SMTP port 25 and needs an IP address for a mail server that is set up to allow it to forward email thru it. The mail server needs to be set up to allow forwarding using port 25 at least from the IP address of the netlogger.
Within the software under setup and email. Please change "Unit Name:" to something other than "Dickson Data Logger".
Why does the display read PROB?
Is the probe plugged in properly?
Is there an extension cable being used? It could be defective
It may be locked up? This can be confirmed by pressing any of the buttons on the keypad, if the unit is locked up there will be no response to button presses and the unit may appear to be working, but the readings won't change, also the chart will not rotate. Remove power and battery, and then re-power.
The sensor board may have fallen out or become partially unplugged. Remove the back panel, the sensor board should be plugged in the center of the main board. If the sensor board is in its socket, you may need to ensure the connection by pressing down on it to make sure it is secure. The pens should respond right away if this is the only cause of the problem.
Is the probe plugged in properly?
Is there an extension cable being used? It could be defective.
Why is my displayed Temperature or RH reading 0?
Replace the batteries, they may be low.
