3. SAFETY INSTRUCTIONS

3.1 General

HUMOR 20 is designed based on state-of-the-art technology, which means it will operate reliably if
it is kept in good condition and operated and serviced correctly. This device may pose a risk if it is
operated improperly by untrained personnel.

Improper use can:

• Injure operating personnel and damage the device itself or other assets belonging to the user.

• Prevent the device from working efficiently and accurately.

Observe the following information to ensure operational safety:

• Only qualified or specially trained staff may operate or perform work on the humidity
calibrator.
Unauthorised changes or modifications are either not permitted or require the express
permission of the manufacturer.

• Read this manual carefully before taking the device into operation. The manual must
also be made available to any person involved in transport, setup, operation, mainte­nance or repair (particularly when loaning or selling the device to a third party).

• Only operate the device if it is in good condition. Any fault must be repaired by authori­sed personnel or by an E+E Elektronik sales partner before it is taken into operation
again.

3.2 HUMOR 20

• Check whether the supply voltage data on the nameplate matches the local supply
voltage. This also applies to the automatic calibration module.

• Only power the humidity calibrator via a grounded power outlet (safety precaution).
This also applies to the automatic calibration module.

• HUMOR20 and automatic calibration module should be placed in a way which allows
an as easy as possible disconnection from the power supply.

• Before opening the water intake, make sure that the humidity calibrator is no longer
under pressure (controller turned to the left as far as it will go; if HUMOR 20 already in
service, display shows RH > 90%).

• HUMOR 20 may only be operated with distilled (deionised) water.

• Before connecting the compressed air or nitrogen supply, make sure that the controller
is turned to the left as far as it will go.

• The device may only be operated with filtered compressed air with a contamination
level of <0.01mg/m³.

• The media supply may not exceed an absolute pressure of 10 bar (pressure gauge
and safety value recommended for use in the supply line).

• If a humidity calibrator is filled with water and ready for operation, it must not be
tilted by more than 20° during transportation. If this is not possible, HUMOR 20
must be drained completely, see section "9.2 Drain water".

• Once HUMOR 20 has been switched off, it must also be disconnected from the
compressed air (because of possible condensation in the lines as the heating is
turned off).

4. OPERATING PRINCIPLE

Dry air

Air or nitrogen under pressure p1 is
fed into chamber 1 and humidified.
The developing saturation vapour
pressure ews is a direct result of the
temperature of the chamber respec­tively the water. Next, the humidified
air is expanded to pressure p and

Pressure [mbar]

Dry air

fed into chamber 2. During expansi­on, the vapour pressure ews is
reduced in the same ratio as the
overall pressure of the air. Therefore,

Vapour pressure

Vapour pressure

the water vapour pressure in
chamber 2 is:

e = ews * p/p1

Thanks to the special design of HUMOR 20 with its high thermal conductivity, chamber 1 always
has the same temperature as chamber 2.

Consequently, if the temperature is the same, the saturation vapour pressure ews of chamber 1 is
identical to that of chamber 2. As a result of the expansion of the humidified air, chamber 2 contains
the water vapour partial pressure e.
From the definition for relative humidity follows for chamber 2:

rh = e/ews = ews * (p/p1) / ews = p/p1

Hence, the relative humidity in chamber 2 is a direct result of the ratio of the pressures in chambers
1 and 2.

The verification has to be executed as follows:

• Turn the humidity controller counterclockwise all the way

• Disconnect the air pressure supply to the Humor

• Display reading > 95 %RH

• Open the water inlet

• Open the measuring chamber (one opening is sufficient,
see picture)

• Read the display after approx. 5 minutes:

Display reading Final conclusion on performance Required action

99.2% to 100.8%

97.0% to 99.2% and 100.8%
to 103.0%

< 97.0% and >103.0%

HUMOR within specifications A high accurate measurement can be

realized

HUMOR outside specifications Adjustment is necessary to obtain the

highest accuracy (see chapter "8.3.2.
Calibration").

HUMOR outside specifications Adjustment is not possible. There is a

problem with the humidity measure­ment / indication and the HUMOR
should be returned to E+E Elektronik
for calibration / repair.

11

7. CALIBRATION AND ADJUSTMENT PROCEDURE

TERMINOLOGY:

Calibration = verification / checking
Adjustment = modification / tuning

The special design of the measuring chamber allows the calibration and adjustment of transmitters
of varying sizes. These include cylindrical sensor probes with a diameter of 8-25.5 mm (0.3-1")
(hand-held instruments, duct-mounted versions, ...) and room transmitters, data loggers, etc. with
maximum dimensions of 100 x 85 x 40 mm (3.9x3.3x1.6") or 95 x 95 x 40 mm (3.7x3.7x1.6").

7.1 Cubical transmitters (room design) with HUMOR 20

HUMOR 20 can also be used to calibrate and adjust room devices
using the Plexiglas cover for the measuring chamber provided in the
scope of supply.
Due to external thermal interference, additional measuring errors may
occur depending on the adjusted humidity and the position of the test
unit in the measuring chamber.

1. Place the test unit in the measuring chamber.

2. Lay the O-ring for the Plexiglas cover in the groove provided in the measuring chamber.

3. Feed the connection cable through the PG screw connection of the Plexiglas cover.

4. Fit the cover and tighten both knurled nuts.

5. Connect the test unit to the supply connections of HUMOR 20.

6. Connect the output signal of the test unit to the internal measuring inputs of
HUMOR 20 (Unit1 RH, Unit2 RH)

7. Select the measuring range in accordance with the output signal of the test unit.
The temperature of the measuring chamber can be displayed by selecting
"Temp." on the measuring range switch.

8.
manufacturer's documentation (however, a minimum of 20 mins is recommended).

9. Use the controller to select the setpoint of the humidity.

10. Compare the values shown in the display with the output signal of the transmitter.

For information on the standard deviations and stabilisation times of the test unit, refer to the

7.2 Transmitter with sensor probe with HUMOR 20

Because of the operating principle, HUMOR 20 has a slightly higher
temperature than ambient. During the measurement process, make
sure that the probe temperature can adapt to the temperature of the
measuring chamber.
To ensure accurate measurements, the cover feedthrough must match
the probe diameter as closely as possible. To ensure that this is the
case, various cover designs are available (see the accessories appen­dix).

1. Fit a suitable measuring chamber cover (note the position and diameter of
the feedthrough) and tighten both knurled nuts.
If inserted, remove the O-ring for the Plexiglas cover.

2. Insert the test unit(s) through the feedthrough(s) in the measuring chamber and tighten the
screw connection(s).

If using the modules EE07 and EE08 (with cables) please note that only the filter caps get
into the measuring chamber of the HUMOR to avoid falsification of the calibration through self
heating effects (see picture on the left).

12

3. Seal the openings of the feedthroughs not in use with the
supplied plugs.

4. Connect the test unit(s) to the supply connections of HUMOR 20 (24V DC).
Make sure that the total power consumption of all transmitters is
not more than 200 mA. In case the transmitters exceed this
maximum, an external power supply has to be provided.

5. Connect the output signal of the test unit(s) to the internal
measuring inputs of HUMOR 20 (Unit1 RH, Unit2 RH, Unit3 RH,
Unit4 RH).

6. Select the measuring ranges in accordance with the output signal of the test units.
The temperature of the measuring chamber can be displayed by selecting
"Temp." on the measuring range switch.

7. Use the humidity controller to select the setpoint of the humidity.

8. For information on the standard deviations and stabilisation times of the test unit, refer to
the manufacturer's documentation (however, a minimum of 20 mins is recommended).

9. Compare the values shown in the display with the output signal of the transmitter.

7.3 Transmitter EE33 Model J with HUMOR 20

To be able to calibrate the transmitter of the series EE33-MFTJ, with the dual probes (Td-probe and
T–probe), a separate available adapter is needed (see chapter 12 ‘accessories’ – adapter for EE33
– model J, part number HA020401) to achieve the highest possible calibration result. The following
steps describe how the series EE33-MFTJ should be calibrated correctly.

1. Plug both air vents of the cover of the measurement chamber with the
plugs supplied with the adapter (see left picture).

2. Insert the Td-probe (Ø12mm) in the measuring chamber through one
of the feed-throughs of the cover and tighten the nut.

3. Insert and tighten the T-probe (Ø6mm) in the adapter and insert in the
measuring chamber through one of the feed-throughs of the cover and
tighten the nut.

4. In case that feed-throughs are not in use, close them with the blind plugs delivered with the cover.
Transmitters delivered after June 2009 have the possibility to heat the
tube of the probe continuously to avoid condensation. This function
must be disabled prior to calibration, by detaching the cover of the
transmitter and removing the “heat”-jumper in the left top corner of the
PCB (see left picture).

5. Connect the test unit to the supply connections of HUMOR 20.

6. Connect the output signal of the test unit(s) to the internal measuring
inputs of HUMOR 20 (Unit1 RH, Unit2 RH).

7. Select the measuring ranges in accordance with the output signal of the test units. The
temperature of the measuring chamber can be displayed by selecting "Temp." on the measuring
range switch.

8. Use the humidity controller to select the setpoint of the humidity.

9. For information on the standard deviations and stabilisation times of the test unit, refer to the
manufacturer's documentation (however, a minimum of 20 mins is recommended).

10. Compare the values shown in the display with the output signal of the transmitter.

After calibration, make sure that the plugs in the air vents in the cover of the measuring chamber are
removed.

7.6 Power failure during the calibration procedure

HUMOR 20

In the event of longer power failures (> 5min.), unlock (pull out) the controller's
rotary knob and turn it anticlockwise as far as it will go. Disconnect the media
supply. Once the power returns and the warm up phase has been completed, the calibration process
can be resumed.

HUMOR 20 with the automatic calibration module

In the event of a power failure, an error message is displayed (see screenshot) and the calibration
must be restarted.

7.7 Ending the calibration or adjustment procedure

If longer idle periods are expected, it is recommended to empty the distilled (deionised) water tank
completely.
For more information, see section "9.2 Drain water".

Remove the supply pressure (compressed air) and turn off the main switch (if applicable, disconnect
the grounding plug).

Design protocol:

In addition, the HUMOR 20 software provides the option of auto­matically generating a measurement protocol.
A ready-made template is defined and on completion of the­measurement filled out automatically with the calculated values.
Immediately after the end of the measurement process, a protocol
in a well-organised format can be generated at the touch of a

button.

E+E Elektronik offers a ready-made standard
template that opens automatically on selection of
the function "Design protocol". This standard
template can easily be altered to meet customer
requirements.

To create a fully customer-specific layout for the
measurement protocol, the help text for the proto­col designer has to be read carefully because of
the wide range of options and functions.
Therefore, the following approach is recommended:

To minimize the effort to create the form /
protocol, just change the text fields or logo of the
standard template only.
To do so, choose "Save as" from the menu and
save the standard protocol under a new file name
of your choice.

To make sure that the standard template will no be
changed, open the protocol designer again and
choose the file just created and change it as
desired.

Changing the logo:

To enter your own logo in the protocol, select the
placeholder (arrow 1). Your logo can be integrated
in the protocol template by clicking on the specified
path in the menu "Properties-Data-Source-File
Name" (arrow 2).

17

2)

Changing text fields:

To change text in the measurement protocol,
choose the required text field (arrow 1) and click on
the icon in the menu
"Properties - Data - Contents" (arrow 2).
You can change the text and format as desired in
the pop-up window "Paragraph Properties" (arrow 3).
In this way, you can easily substitute the German
text for textin the relevant language.

3)

New protocol template:

If you would like to create a complete new protocol
template, refer to the information in the protocol
designer's help text.

If you have any questions, pleased contact the E+E

8.3.2 Adjustment / Calibration

Temperature calibration:

Only possible in the "CUSTOMER calibration" mode.
The temperature is equalised with a temperature standard.

A stabilisation time of 2h is recommended.

1. Insert an external temperature standard into the measuring

chamber.

2. Enter the reference value in the input field.

Important: Temperature must be within the range 23°C ± 10°C.

3. With "Store" the adjusted temperature value is implemented.

Monitoring sensor calibration:

Only possible in the "CUSTOMER calibration" mode.
This function can be used to adjust 2 points of the humidity trans­mitter integrated in HUMOR 20 for monitoring purposes.

Procedure:

1. Acclimatise HUMOR 20 to the ambient conditions

(temperature homogeneity).

2. HUMOR 20 should run for an additional 2 hours after the

warm up phase.

3. Set the lower setpoint to 30% RH.

4. Once the stabilisation time has expired (30 mins), equalise the

"Monitoring Sensor" to the reference value of HUMOR 20.

5. Set the upper setpoint to 70% RH.

6. Once the stabilisation time has expired (30 mins), equalise the

"Monitoring Sensor" to the reference value of HUMOR 20.

Analog Measurement Input Calibration:

With this function, the analog measurement inputs of the Humor20
(1-4) can be checked:

1. Select with Switch1 (see 6.1) either a current or a voltage
range.

2. Select with Switch 2 (see 6.1) the measurement input to be
tested.

3. Connect the external signal source with the selected Humor20
measurement input (1-4).

4. Set the analogue signal from the external source (0 – 10 V or
0 – 20 mA)

5. In the display the measured value will be indicated.

22

Reset to Factory settings:

All of the adjustment's calibration data is reset to the factory
calibration default values.

8.3.3 Pressure Compensation

This function is used to equalise the two pressure transmitters
of HUMOR 20.

For accurate measurements, the equalisation should be
performedevery 4 weeks.

Follow the instructions in the info field and
press the button "Store".

Once the equalisation is complete, check that "
100% RH" is shown in the HUMOR 20 display.

Measurement points count:

Enter the number of measurement points and confirm your entry by pressing "Apply".

Set measured values automatically:
Checkbox selected: The test unit's measured value at the measuring input of HUMOR 20 is set auto­matically once the stabilisation time has expired.
Checkbox not selected: The program waits for the measured value to be entered manually once the
stabilisation time has expired.

Log measured values additionally in
fixed interval:

If you select this checkbox, the test unit's
measured values will be logged by the
measuring input of HUMOR 20.
The measured values are stored in the file
"MeasLog.csv" in the program directory of
the HUMOR 20 software.

Now you can set the measurement points:

Target RH:
Enter the humidity value of the measurement point, e.g. 20 for 20% RH.

Target time [min]:
Enter the required stabilisation time in minutes (e.g. 20 for 00h 20min or 80 for 01h 20min).

Spec. dev. RH:
Enter the permitted tolerance for the measurement point. You can only enter numerical values (e.g.
2 for ±2% RH).

Once all the measurement points have been fully configured, you can start the measurement by
pressing the "Start" button.

If using an automatic calibration module, turn the humidity controller to the right (clockwise) as far
as it will go, refer to chapter 6.3.

The automatic calibration module now
adjusts to the first measurement point.

During this adjustment procedure, the
orange LED "auto" on the automatic cali­bration module flashes. Once the setpoint
has been reached, the LED lights up con­tinuously.

If the measurement point is reached within
a range of ±1% RH, the stabilisation time
for the measurement point begins to run.
Once the stabilisation time has expired,
depending on whether the checkbox "Set
measured values automatically" has been selected, either the system enters the value of the measu­ring input of HUMOR 20 or waits for a manual entry.

Once the measurement is completed, the automatic calibration module adjusts the humidity to 10%
RH (orange "auto" LED goes out). The measured values are stored in the program directory

[.....\E+E Elektronik\HUMOR-20\MeasData].

The file name consist of the current date and time e.g. 2008-08-25_12_10_05.hmf

Note: If the measurement is aborted, no measured values are stored!

8.5 Fixed RH Value (only available when using an automatic calibration

module)

The humidity control knob of the Humor20 has to be turned to the right (clockwise) all the way to the
stop, see chapter 6.3

Start Button:
as soon as the desired value is entered and the
"Start-Button” is pressed, the desired humidity in the
measurement chamber will be set by the Automatic
Calibration Module (orange “auto” LED blinks or illu­minates)
Stop-Button:
activating the “Stop-Button” will end the control of the
Automatic Calibration Module (orange “auto”
LED not illuminated); in this way, a humidi­ty level of 10 %RH will be set in the measuring
chamber of the Humor20.

9. MAINTENANCE

The distilled (deionised) water should be changed every 8 weeks.
If the unit is idle for longer periods, all the water should be removed.

9.1 Re-fill water (at error message - waterlevel low)

1. Turn the humidity controller all the way to the left and wait until the
message "OUT OF SPEC" is displayed.

2. Remove the screw plug.

3. Fill with distilled (deionised) water (when the error message
"Waterlevel low" is displayed, a max. of 1,000 ml can be added).

4. Replace the screw plug and tighten.

5. If the maximum fill level is exceeded, the error message "Waterlevel high" is displayed, and
water must be removed until the message on the display disappears.

6. After filling, wait for a stabilisation time of around 20 mins (the higher the difference in
temperature between the water and the humidity calibrator, the longer the stabilisation time
ought to be).

7. HUMOR 20 is ready for operation.

9.2 Drain water (at error message - waterlevel high or long idle periods)

1. Turn the humidity controller all the way to the left and wait until the
message rel.HUM high appears in the display.

2. If you are using the automatic calibration module, connect the
compressed air supply directly to HUMOR 20.

3. Connect the water drain hose to the discharge nozzle.

4. Turn the humidity controller slowly to the right until water drains
out.
a) Until the "Waterlevel high" message disappears.
b) Until the saturation chamber is completely empty. To make
sure that the chamber is completely dry, flow air through the
device for a short time.

5. To end the drainage process, turn the humidity controller to the
left again as far as it will go.

6. Disconnect the compressed air and the water drain hose.

7. HUMOR 20 can now be turned off.

9.3 Cleaning

For cleaning the HUMOR20 and automatic calibration module a dry drapery should be used.

1st line: Displays moisture () or error ()
2nd line: Status bar () and actual value of the test unit on HUMOR 20

The humidity calibrator is equipped with an auto diagnostic system. It issues different operating or
error messages depending on the operating status or error. You can remedy the cause of the mes­sages as follows:

CAUSE REMEDY

10.1 Humidity - display flashes

1. After a sudden change in the setpoint, the

measuring chamber has not reached the
desired value immediately. As soon as the diffe­rence between the relative humidity shown in
the measuring chamber and the setpoint
exceeds a defined range, the display starts to
flash.

2. Water in the measuring chamber or internal

lines.
This error is usually caused by transporting a
HUMOR 20 device filled with water or connec­ting compressed air when the humidity control­ler has not been turned all the way to the left.

Wait for the stabilisation time to end (after a few
minutes, the display should stop flashing auto­matically).

Dry the measuring chamber with an absorbent
cloth. Drain the water, and let compressed air or
nitrogen flow through the device for a lengthy
period. This is achieved by specifying a
setpoint of 75% on the humidity controller.
During the purging (drying), the display flashes
and the warning WATERLEVEL LOW is shown.
The drying process lasts around 48h and
should be monitored by a test unit. The drying
process is complete as soon as the test unit
shows a relative humidity of < 15%.
This process can be accelerated by using dry
compressed air or dry nitrogen.

10.2 Warning: OUT OF SPEC

A humidity setpoint > 95% RH was specified or
< 10% RH was selected.

10.3 Warning: WATERLEVEL HIGH

The maximum fill level for distilled (deionised)
water has been exceeded.

28

Device is operated outside of the working
range.

Empty water until the warning disappears.

10.4 Warning: WATERLEVEL LOW

The water level is below its minimum. Add distilled (deionised) water.

10.5 Error message: heat defect

HUMOR 20 has not reached its operating
temperature.

10.6 Error message: pressure excess

A humidity setpoint < 8% RH was selected. The
humidity calibrator may have been damaged by
the high pressure. The specified accuracy
cannot longer be guaranteed.

10.7 Humidity - display is incorrect

Incorrect display, e.g. because of an error in the
electronics.

10.8 Stabilisation time too long

Valve defect.

Contact your E+E Elektronik sales partner.

Contact your E+E Elektronik sales partner.

Check HUMOR 20.
Turn the controller to the left as far as it will go
and disconnect the compressed air. After a sta­bilisation time of 2h, the display should show
100 ±2%RH. If this is not the case, contact your
E+E Elektronik sales partner.

Check the flow.

1. Drain all the water completely and refill the
humidity calibrator with exactly 1000 ml of dis­tilled water.

2. Specify a humidity setpoint of exactly 20% RH.

3. Turn the humidity controller all the way to
the left and measure the time it takes for the
value 80%RH to appear in the display.

- If the time measured is < 80sec, the
flow is correct and within the working
range.

- If the process takes much longer, contact
your E+E Elektronik sales partner.

The response time of HUMOR 20 for a jump in
humidity from 25 to 80% RH and from 80 to 25% RH
is shown in the graph. A jump to a lower value requires
approx. 1 minute, while a jump to a higher humidity
value requires approx. 3 minutes.
The required stabilisation time is determined primarily
by the test unit.
Considering the response times of instruments now
available on the market (equipped with standard
filters),
a stabilisation time of approx.20 minutes /
measurement point can be expected.

29

10.9 Leakage in filter set
CAUSE REMEDY

You will hear if there is a leakage in the filter set
(escaping air).

Disconnect the compressed air supply
and check the pressure.
Make sure the supply is at least 8 bar. Reconnect
the pressure supply.

10.10 Electronic defect - replace electronics

Replacing the electronics:

1. Disconnect the humidity calibrator from the supply voltage.

2. Loosen the screws (see Fig. 1).

Measuring Chamber

The construction of the measuring chamber allows the calibration and adjustment of cylindrical sensor
probes with a diameter of 8-25.5mm (0.3-1”) (hand-held instruments, duct-mounted versions, ...) as well
as of cubic measuring units (room transmitters, data loggers, ...) with maximum dimensions of
100x85x40mm
By using the Plexiglas cover (standard supply), it is possible to calibrate and adjust compact room devices
(e.g., the EE10) with the HUMOR 20.
The overall accuracy of the calibration is influenced by the absence of the metal cover. The additional error
depends on the position of the specimen in the chamber as well as on the relative humidity.
