Common Information
Calibration information
All DEWETRON modules are calibrated at 25°C after a warmup time of 30 minutes and meet their speci-
cations when leaving the factory. The time interval for recalibration depends on environmental conditions.
Typically, the calibration should be checked once a year.
Calibration certicates are available from DEWETRON as an option. DEWETRON offers several types:
NIST traceable DEWETRON calibration certicate (USA CAL LAB only)
ISO traceable DEWETRON certicate (European CAL LAB only)
Calibration certicate according to ÖKD (equivalent to DKD)
RS-232/485 interface
HSI modules can be congured via RS-485 interface. DEWETRON instruments include an internal RS-
232/485 converter and interface. This converter allows communication with all DEWETRON signal condition-
ing modules. To communicate with the modules, the RS-232 interface must be set to the following param-
eters:
baud rate: 9600
data bits: 8
parity: no parity
stop bits: 1
handshake: not required
