4. Output signals menu:
1. Current output. Sets the zero and span in concentration units that correspond to 4-20 mA
output. The signal range 0-20 mA can also be selected. The 0 will be slightly above 0 mA,
typically 0,06 mA. An active HOLD function locks the signal during prism wash by the Relay
Unit. When the HOLD function is inactive, the wash results can be seen as a negative peak in
the output signal.
2. External current output. Defines the scale for the External Output Unit (Section 10.1) the same
way as above. In addition the source has to be selected from the list Concentration/Standard RI
(25 °C)/Temp °C/Temp °F.
3. Serial output. The format is to be defined, see Section 3.7.
5. Temperature menu:
The temperature calibration is made through this menu, see Section 5.8. It is also possible to select the
temperature display unit in the normal display as °C/°F. A high temperature limit can be activated and set
for a "High process temperature" message, Section 6.3.
6. Standard RI (25 °C):
Gives the calibration parameters for the bench calibration value with standard RI liquids, Section 5.4. The
RI (25 °C) can also be added to the normal display.
7. Language
Selection of display language: 1. English 2. German.
8. Divert control
Supports the K-Patents Divert Control Unit DD-01, see separate Instruction Manual for the Digital Black
Liquor Divert Control System.
9. Password
A software password can be selected to prohibit unauthorized calibration, see Section 2.11.
2.9. COMPATIBILITY WITH EARLIER K-PATENTS REFRACTOMETER SYSTEMS
The model PR-01-S has been preceded by models PR-01, PR-01-E and PR-01-B.
Sensor
The sensors of all models are using identical mounting parts, so e.g. a PR-01-B refractometer can be
replaced by a PR-01-S without any process pipe changes. The critical measure, i.e. the distance between
the prism and the process connection, is unchanged.
Interconnecting cable and Indicating transmitter
The PR-01-S cable, and also the transmission, is different from earlier models. Neither Sensor nor
Indicating transmitter of the model PR-01-S can be combined with any corresponding unit of the earlier
models.
