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.
Operation

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.

Overview
2
H5850 is a versatile handheld device for
humidity measurement of solids and bulk
materials, designed to operate with COMECO
bulk-material moisture probe RHP. Using a
built-in Pt1000 sensor, H5850 can also
indicate the medium temperature. The device
is equipped with a 4-digit display showing
moisture-content, relative humidity and
medium temperature. The device is offered
with two 1.5 V AA batteries and features a
special automatic-battery-control function. The
numerous features of H5850, along with its
high accuracy and low consumption, make it a
useful instrument for bulk-material moisture
measurement.
Declaration of Conformity
The undersigned hereby declares, on behalf
of COMECO Inc., that this device has been
manufactured in compliance with standards
EN 61010 and EN 61326 and meets the
requirements of Directives 89/336/EEC,
2004/108/EC and 2011/65/EU
(batteries not included).

Waste Disposal
Do not dispose
of electronic
devices together
with
household

implementing
the WEEE Directive 2002/96/EC
on the Waste Electrical and Electronic
Equipment.
Calibration
7
Calibration is available
in programming mode
only if humidity is
selected as measured
channel!
The samples’
moisture content
must differ at least on
5%. As bigger is the
difference as
accurate will be the
calibration!
The calibration
procedure can be
interrupted at any
time by pressing
+ .
simultaneously.
A humidity measurement calibration MUST be
done when use H5850 with an “unknown” (new)
material. It can also be done every time in order
to improve measurement accuracy.
Calibration procedure requirements
- H5850 with connected RHP probe
- 2 samples of material with preliminarily
known (laboratory defined) moisture content
or relative humidity
Calibration procedure steps
1. While H5850 is in programming mode, select
CAL and confirm with .
For a half second the display shows Lo P,
which reminds the user to go to step #2.
2. Enter the moisture content value of the
sample with lower humidity by changing the
previously stored value with + .
3. Fill the RHP probe with the material from the
sample with lower humidity and wait approx.
10 seconds.
4. Press to start lower-point calibration.
5. When H5850 display shows HI P, enter
the moisture content value of the sample with
higher humidity by changing the previously
stored value with + .
6. Fill the RHP probe with the material from the
sample with higher humidity and wait approx.
10 seconds.
7. Press to start higher-point calibration
and calculating calibration coefficients.
8. If the calibration has been successful, H5850
shows the message dOnE and, after 0.5
seconds automatically exits calibration mode.
9. After an unsuccessful calibration H5850 will
show Err message. It may happen if the
samples’ moisture content difference is lower
than 5% or if the RHP signal is too small
(under 2mV/%). In this case change the
samples or check the probe for damages.
Programming I

Display offset and
Temperature unit
appear only if RTD is
installed and
temperature is
selected as measured
channel!
Humidity type and
Preset material appear
only if humidity is
selected as measured
channel!
If no key have been
pressed for5 s, H5860
exits programming
mode storing only the
confirmed changes!
The default
temperature unit is
degree Celsius!
H5850 will switch to
degree Celsius after
power reset.
The following parameters can be set by the user in
Programming mode:
- Display offset (0F t)
- Temperature unit (Un1t)
- Auto power-off time (toFF)
-Humidity type (AHrH)
- Preset material (StUF)
Enter programming mode by pressing +
keys simultaneously. Use one of the same keys to
select one of the above parameters.
Confirm your choice with .
Auto power-off time
The toFF parameter defines the time between the
moment a key has been pressed for the last time and
the moment the device turns itself off automatically.
The auto-power-off time is user-selectable in the
range from 0 to 30 min.
In programming mode, select toFF parameter with
or
and confirm it with .
Read the last parameter value on the display.
Use
to increase and to decrease the value
and confirm with .
Press + to exit without change.
Display offset
The 0S t parameter linearly offsets the
temperature reading on H5850 display.
In programming mode, select 0S t parameter
and proceed as above.
Temperature unit
The Un1t parameter defines the temperature
measuring unit. In programming mode, select
Un1t parameter and proceed as above selecting
Celsius or Fahrenheit degrees
(.C
or
.F).
Programming II
5
Humidity type
The AHrH parameter defines what kind of
“humidity” will measure H5850 - moisture content
(absolute humidity) or relative humidity of the
material tested. In programming mode, select
the AHrH parameter and proceed as the other
parameters selecting moisture (AH.o)or
relative humidity (rH.o) to be measured.
Preset material
H5850 can store calibration data (see 'Calibration')
for up to 5 different materials. The StUF
parameter defines what calibration data will be
used by H5850 to calculate humidity value. This
feature is helpful when the same type of material
must be tested very often. In programming mode,
select the StUF and proceed as above selecting
the desired pre-calibrated “material” from 1 to 5
(StF1 ... StF5).
