Operation with RPH probe
♦
Before applying new material always
clean and dry the internal probe
surface.
♦
Fill the probe with the material to its
upper edge and flat the surface.
Do not overfill or under fill!
Do not press or stuff the material!
♦
For calibration purposes use two
samples with enough different
moisture content, but with the same
size of the particles.
♦
In order to achieve the required
measuring accuracy, the composition
and the particles' size of the material
being tested must be the same as the
calibration samples.

Notes
1. If the resolution is integer (no
decimal point), H5850 will
round off the readings with a
decimal part greater than or
equal to 0.5 (e.g., if the
measured value is 12.7,
the unit will indicate
13
)!
2
. After recovery from power
supply failure (for example,
due to battery replacement),
H5850 will display the
readings without decimal
point (integer) until the other
resolution is selected!
Notes
1. Using probes without
Pt1000 sensor does not
allow temperature
measurement with H5850!
2. The default measuring
channel (after power-on) is
always moisture/RH!
Turning ON/OFF
♦
Turn on by pressing the
key once.
The test string
8888
appears on display
and H5850 enters measurement mode.
♦
Turn off by pressing the
key once.
The unit indicates
0FF
and turns itself off.
Display resolution selection
Display resolution can be changed alternatively
with
The reading can be displayed either
as integer number or as number with one digit
after the decimal point.
After pressing the key, read for half a second
respectively
0
or
)0
.
Changing measured channel
Besides the material humidity, H5850 can also
measure its temperature, if the probe is
equipped with Pt1000 temperature sensor.
Press once
key to check which channel is
being measured - moisture/RH (
AH.o
/
rH.o
) or temperature (
t .C
/
t .F
).
Press and hold
to change the channel.
Measurement mode
In measurement mode H5850 measures
material moisture/RH or temperature depending
device settings and connected probe and.
One measurement cycle lasts approximately
0.5 s and display readings refresh after its end.
Low-battery indication
H5850 monitors the battery voltage, and when it
drops bellow the critical (approx. 2.5V), each 10
seconds the device displays
bAtt
for about
0.5 s. It reminds you to replace the batteries.
