2034 TERTIARY_VALUE_TYPE None None, ORP, rH When a metal electrode is used in combination with a glass and
reference electrode one has the possibility to measure a tertiary
value:
2035 TERTIARY_VALUE - -1500 to 1500 mV, The third value is expresed in mV or rH units
0 to 55 rH
2036 TERTIARY_VALUE_RANGE -1500 -1500 to 1500 mV, The high and low range limits for the tertiary value.
to 1500 0 to 55 rH
2037 TERTIARY_ZERO 0 -120 to 120mV Redox offset can be set in mV.
2038 GLASS_IMPEDANCE - 1MΩ to 2 GΩ (HI) Value that indicates the state of the glass membrane.
1kΩ to 1MΩ (LO) Depending on the jumper setting the range is set to High or Low.
2039 REFERENCE_IMPEDANCE - 1MΩ to 2 GΩ (HI) Value that indicates the state of the reference system.
1kΩ to 1MΩ (LO) Depending on the jumper setting the range is set to High or Low.
2040 ALARM_SUM -
2041 DEV_ALARM - Device Alarm is used to give the status of the transmitter. Device_
status in RB displays the device Alarms.
2042 LOGBOOK1_RESET - Reset the pointer to the first (oldest) event in logbook 1.
2043 LOGBOOK1_EVENT - Event whereto the pointer is referenced. When parameter is read,
the pointer is increased by one.
2044 LOGBOOK2_RESET - Reset the pointer to the first (oldest) event in logbook 2.
2045 LOGBOOK2_EVENT - Event whereto the pointer is referenced. When parameter is read,
the pointer is increased by one.
2046 LOGBOOK_CONFIG - Per event one can decide whether it should be logged and in which
logbook (1 or 2) it should be logged.
