Conditions of correct programming of the data pairs
Left column "L"
The table must always start with: L(1)= 0 and r(1)= value (assigned to 0 level)
The table must be ended either with the 32
by a level value "0" e.g. L(j<32)= 0.
The EchoTREK will ignore data after recognising level value "0" with serial number other than "1".
If the above conditions are not met, error codes will be displayed (see chapter: Error Codes).
6.7 Informational Parameters (Read Out Parameters)
P60:
Overall operating hours of the unit (h)
Indication varies according to the elapsed time:
Operating hours
0 to 999.9h
1000 to 9999h
Over 9999h
P61:
Time elapsed after last switch-on (h)
Indication same as in P60.
P64:
Actual temperature of the transducer (°C/°F)
P65:
Maximum temperature of the transducer (°C/°F)
P66:
Minimum temperature of the transducer (°C/°F)
In case of a breaking in the temperature measuring Pt10 element „PtErr" will be displayed (See Chapter 7). The transmitter will perform
temperature correction corresponding to 20ºC.
