Setup

The EE371 probe is ready to use and does not require any configuration by the user. The factory setup
of EE371 corresponds to the type number ordered.
The scaling of the analogue output and settings of the relay thresholds can be changed with the free
EE-PCS Product Configuration Software, free download at www.epluse.com/configurator
Use either the serial interface cable HA010604 or the EE-PCA Product Configuration Adapter with the
cable HA011063 to connect the EE371 to a PC.

Calibration / Adjustment

7.1

Definitions

Calibration
The calibration documents the accuracy of a measurement device. The device under test (specimen) is
compared with the reference and the deviations are documented in a calibration certificate. During the
calibration, the specimen is not changed or improved in any way.
Adjustment
The adjustment improves the measurement accuracy of a device. The specimen is compared with the
reference and brought in line with it. An adjustment can be followed by a calibration which documents
the accuracy of the adjusted specimen.
The dew point temperature adjustment of EE371 can be performed with the free EE-PCS Product Con-
figuration Software, free download at www.epluse.com/configurator

Customer adjustment - Dew Point

The dew point adjustment can only be performed if the span between the air or gas temperature Ta and
the reference dew point temperature Td is higher 60 °C (108 °F).
Example:
For Ta = 20 °C (68 °F), the reference Td must be < -40 °C (-40 °F).
