Troubleshooting

No communication

• Verify that you have the correct version of Dickson

software installed on your PC. Version 7.2 or higher is

required for models SR200 and TR220.

• 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 it's 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 open the logger,

remove the battery, reinsert it and then try all COM

port and cable combinations again.

• If possible, try another PC

Indicator

This indicator will flash every 10 seconds ONLY when the

unit is sampling and operating properly. If the indicator is

not flashing, please verify the following:

• The logger memory may be full; download the data

and clear the memory.

• Sampling may not be activated. To start sampling

clear the memory.

• 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.

Battery

The battery will operate the logger for 1.5 years at room

temperature. Operation of the logger at the temperature

extremes, in real-time mode for prolonged periods, or

sample intervals of less than a minute, will significantly

reduce battery life. To replace the battery, simply remove

the 4 screws in the back of the logger, replace the

battery, and reassemble. Make sure that you place the

positive (+) pole towards the + sign on the circuit board.

The Battery Level Monitor on the Setup screen displays

the battery voltage and a Low Battery Warning when

replacement is needed.
