Em5b
PROBLEM: 3
ECH2O Utility tells me it lost connection with ECH2O device.
SOLUTION:
A noisy serial connection can sometimes disrupt the connection be-
tween ECH2O Utility and the Em5b. If this error happens regularly
when you are direct connected to your device, try setting your baud
rate lower or increasing the number of times ECH2O Utility retries
the commands it sends to your device. Choose the "Communica-
tions" tab in Preferences to set the Maximum Baud Rate lower or
increase the number of Direct Connect Retries.
PROBLEM: 4
My logger stopped making measurements.
SOLUTION:
Here are some steps to try:
1. Make sure you are not connected to the logger. ECH2O loggers
are not designed to make sensor measurements when connected
to the computer. Please remove the serial cable from the logger
to enable making and storing sensor measurement.
2. Make sure the measurement interval is not set to 0. ECH2O
loggers do not make any measurements when the measurement
interval is set to zero.
PROBLEM: 5
My data shows " * * * " in the Scan Ports window or in the data
file.
SOLUTION:
The three stars mean the raw data was out of the expected range
