With entry of this code word, the protected parameters can be

Z17 Device type
0 TME400-VM (default)
1 TME400-VC
2 TME400-VM MID
3 TME400-VC MID
Z24 Display active max.
0 1 minute (default)
1 5 minutes
2 60 minute test
The time during which the display is active for tests is selected as 60
minutes. In general, however, it must be observed that higher energy
consumption is associated with this time, so this time should be se-
lected as short as possible, if possible.
Z25 Volume metering mode
0 1-channel without errors (default)
1 1-channel stop on error
2 1-channel run on error
3 1-channel start / stop
4 1-channel reset
5 2-channel stop on error
6 2-channel run on error
7 2-channel without X:Y error
With 1-channel measurements (0, 1, 2, 3, 4), the Z04 and Z05 pulse
comparison is not activated.
An entry for sensor type 2 is superfluous and has no further signifi-
cance.
Z26 Characteristic correc-
tion
If the TME400 is supplied with a current supply, the TME400 ena-
bles a characteristic correction via a polynomial. This correction
must be activated with coordinate Z26. With this polynomial correc-
tion, the corresponding percentage deviations of the turbine meter
from a reference standard are determined for fixed percentage flow
rate values. From these deviations, a polynomial function which ide-
ally reflects the curve running through these points is calculated. The
coefficients of the polynomial A-2, A-1, A0, A1 and A2 are adjusted
by the manufacturer in the coordinates B10 to B14 or can be entered
there when the manufacturer of the turbine meter provides these val-
ues.
Note
The HF output pulses (X3 pulse 1) are always uncorrected!
