DISPLAY FIELD NAME PURPOSE CONTENTS SECTION
1. PRESSURE1 Measured
pressure
Displays pressure
measured by the
active Q-RPT Numerical pressure value and sign. 1.2.3
2. UNIT Unit of
measure Identifies unit of
measure in which
pressure values are
displayed Pressure unit abbreviation 3.7.3
3. M Measurement
mode Not used in the
E-DWT-H.
RPM4-E-DWT
supports gauge mode
only.
<g > for gauge mode
None
4. h Head
pressure
indicator Indicates whether a
fluid head correction
is applied to
PRESSURE1 <h> the fluid head is not zero
<blank> fluid head is zero

5. z AutoZero
indicator Indicates whether
the AutoZero function
is ON or OFF for the
active
Q-RPT and
measurement mode
<z> AutoZ is ON
<blank> AutoZ is OFF
