1.
Input
A
for air speed, pressure and Pt100 temperature probes - DIN45326 8-pole connectors.
2.
HOLD
symbol: appears when you press HOLD.
3.
Battery symbol: indicates a low battery level (fixed symbol) or the auto shut-off mode disabled
(flashing symbol).
4.
Display lower line relating to the module connected to input B.
5.
RS232
symbol: flashes while transferring data to the instrument serial line.
6.
REL symbol: appears if you press REL to indicate the instrument is collecting relative
measurements.
7.
AVG
symbol: the display shows the average values detected through the RCD function.
8.
Unit of measurement related to the variable viewed on the display upper line (probe connected
to input A).
9.
<
REL/Esc
> key: displays the difference between the current value and the one logged when the
key was pressed. Within the programs, it cancels the operation in progress without changing the
instrument parameters.
10.
<
MEM/Enter
> key: stores the current value to be used for flow calculation. In the programs, it
confirms the current value.
11.
<
UNIT A/Pitot Tcomp
> key: selects the unit of measurement for input A. In the programs, it
sets manual temperature to compensate the measurement provided by the Pitot tube.
12.
<
PRINT/Baud Rate
> key: activates a data transmission through the RS232 serial output. In the
programs, it sets the serial line baud rate.
13.
<
LOG Start-Stop/Dump Log
> key: in measurement mode, it starts and stops storage. In the
programs, it starts the download of stored data and increases the displayed parameter.
14.
<
Probe ZERO/Delete Log
> key: allows to set to zero hot-wire speed probes and differential
pressure gauges. From the programs, it allows to clear memory data.
15.
RS232 9
-pole connector.
16.
<
RCD Start-Stop/RCD Clear
> key: starts and stops the Record function; in the programs, it
resets the previous Record measurements and decreases the displayed parameter.
17.
<
PROG
> key: activates the instrument programs.
18.
<
Max-Min-Avg CALL
> key: recalls the maximum (MAX), minimum (MIN) and average
(AVG) values, measured through the Record function.
19.
<
UNIT B/DuctCalc
> key: selects the unit of measurement for input B. Within the programs, it
makes the calculation of pipe flow.
20.
<
HOLD/SampleTime
> key: freezes current measurements. Inside the programs, it sets the
number of measurements to calculate the current average.
21.
<
ON/OFF
> key: switches on and off the instrument.
22.
Temperature unit of measurement related to the two inputs.
23.
Unit of measurement related to the variable displayed on the display lower line (probe
connected to input B).
24.
MAX
symbol: the display indicates the maximum values measured through the RCD function.
25.
MIN
symbol: the display indicates the minimum values measured through the RCD function.
26.
RCD
symbol: indicates that the record function is active.
27.
LOG
symbol: indicates that the logging function is active.
28.
Display upper line related to the probe connected to input A.
29.
10
3
symbol: indicates the multiplicative factor (x1000) for channel A.
30.
Input
B
for relative humidity probes and Pt100 temperature probes – DIN45326 8 - pole
connector.
