Ordering information
The order number structure shown below is used to specify a
fully functioning transmitter. The selection of the operating data
(type of source, measuring range, characteristic etc.) is made
according to the following rules:
• Operating data already set in factory to default values:
The default settings can be obtained from the list of parame-
terizable operating data (see "Special operating data"). The
presets can be modified by the customer to match the require-
ments precisely.
• Operating data set on delivery according to customer require-
ments:
Supplement the Order No. by "-Z" and add the Order code
"Y01". The operating data to be set can be obtained from the
list of parameterize operating data. The Order codes A
7
7
to
K
7
7
for operating data to be set need only be specified in the
order if they deviate from the default setting.
The default setting is used if no Order code is specified for op-
erating data.
The selected parameters are printed on the transmitter's rating
plate.
