Maintenance and Trouble Shooting
6.1 Maintenance
Sustained operation of the H-2191 is almost maintenance-free. There is no desiccant or serviceable
parts to maintain. It is always best to keep the unit as dry as possible and out of direct sun light.
6.2 Trouble Shooting
It is unlikely that this manual will ever contain trouble shooting tips to cover every problem that may
be encountered. Feedback from customers is very valuable and greatly aids in the quest for constant
product enhancement. Please feel free to call the factory for technical assistance, and also to share
solutions you have found to past problems. The following paragraph present some possible solutions
to a few problems that may be encountered.
Will not answer when called:
1. The H-2191 may be busy communicating with the connected device. If so, it may not answer
the call. If connected to a W
ATER
LOG series data logger, the H-2191 will be activated
®
when the data logger turns on to make a measurement, the H-2191 will be active until the
measurement is complete and data has been sent to the H-2191 data value boxes. This
normally takes 15 seconds but can be longer based on the settings and the sensors that are
connected. Wait for a minute or so and try again.
2. If the line is busy, someone else may be talking to the H-2191 or it is trying to make an out
going calls based on some alarm condition.
The “Press 1 For New Measurement” option responds with “No Data Available”:
1. The connected data logger may not be responding to commands from the H-2191 to take a
new reading. Check the cable between the H-2191 and the connected device. Make sure the
connected device is functioning properly.
2. Check the voice modem setup menu options to ensure the data to be sent to the H-2191 is
defined correctly.
3. The H-2191 may timeout before the data is ready to be sent from the data logger. Increase
the timeout associated to waiting for data. The default is 30 seconds but can be increased to
250 seconds.
