measured fluid may be limited, or the empty threshold of the empty pipe and the range
of the empty pipe are incorrectly set.
2.
Check if the signal cable is OK or not.
3.
Check if the electro-poles are OK or not.
4.
Let the flow be zero, then the displayed conductivity should be less than 100%.
5.
Resistances of SIG1 to SGND and SIG2 to SGND are all less than 50kΩ (conducti
vity of
water) during measurement operation. (Resistances should be measured by means of
multi-meter with the pointer for a better understanding of charging well.)
6.4
Measure Flow Disallow
If measured fluid full of testing pipe of sensor, check if the signal cable is OK.

Further Errors and Countermeasures
1.
When the device indicates 0.0000 even though there is a volume flow and an “
R
”
glows
in the display and the signal quality Q is ok, there must be a different error. In many
cases, this means that the zero point has been set incorrectly. Go to menu M432 and
reset the zero point.
2.
The displayed volume flow is obviously too low or too high:
a)
Probably, the volume flow in window M44 has been entered manually. Set this
value to “0“.
b)
Problems with the sensor installation
c)
Possibly, the display was set to “0“via
M42 despite an existing volume flow.
Repeat the zero-point setting and make sure that there is no flow in the pipe.
3.
The real battery life is shorter than the value stated in M07.
a)
The battery has exceeded its life cycle.
b)
The battery has not been charged completely or the charging procedure has been
interrupted too frequently. Charge the battery again. If the problem persists,
contact Tek-Trol LLC.
c)
When the battery voltage is between 3.70 and 3.90 V, discrepancies between the
estimated and the actual transit time can occur.
