7.2 Connections
Interface
: Connection for electrical isolated interface
adapter (accessories: HND-Z031, -Z032 or -Z033)
Connection for meas. Probes *)
Temperature input T2:
Connection for NiCr-Ni-
temperature probe (type K) for surface temperature
measurements etc.
The mains socket is located at the left side of the measuring instrument.
*) The following sensor types can be connected to the connection socket:
-HND-FF31
(atmospheric humidity and temperature T1)
-HND-FF33
(flow speed air, 0.55..20m/s)
-HND-FF32
(flow speed water, 0.05..5m/s)
7.3 Displays
Depending on the measuring probes/sensors connected the following measuring
results can be displayed:
HND-FF31
Main display:
r.H.: relative atmospheric humidity in %
Secondary display:
possible views:
T1: temperature of the HND-FF31
Td: dew point temperature of air
kJ/kg: enthalpy
with surface temperature probe at T2:
T2: surface temperature
ΔTd: dew point ratio = T2 - Td
The desired secondary display view can be selected by pressing the
-key.
HND-FF32 or HND-FF33:
Main display:
m/s
: flow rate
Secondary display:
possible views:
t.AVG
: time left till average flow value in
seconds will be displayed
with temperature probe at T2 and as
soon as the averaging time has been
reached: T2: temperature
