1 Scope of Document

This instruction manual refers to HygroGen2 running software version 2.1. To determine the software version your instrument is running, please refer to the Settings Screen as shown in section 3.4.5

. For

version 1.x.x, the software revision number is displayed by pressing the “HG Info” button; for version

2.0, select “Info” from the “Service” drop-down menu; for version 2.1, select “HygroGen2 Info” from the “Support” drop-down menu. An equivalent manual is available on

www.rotronic.com for

HygroGen2 instruments running software versions 1.x.x and 2.0.

If you are running version 1.x.x, it is strongly recommended to upgrade to version 2.x. Please see

section 3.2 (Upgrading From Previous Versions)

for installation instructions.

1.1 Introducing the HygroGen2

The HygroGen2 is a generator of controlled relative humidity and temperature environments, primarily for use in calibrating humidity instrumentation, but is also well suited to the calibration of temperature instrumentation, particularly those used for the measurement of temperature in air.

It is a completely self-contained, portable unit requiring no external resources except mains power. This allows technicians to perform calibrations in the laboratory, workshop or on-site.

The HygroGen2 uses a mixed flow method for generating the %rh required by the user. A desiccant cell provides a source of low humidity and a piezoelectric humidifier generates high humidity. A Peltier element is used for heating and cooling the chamber. Measurement and control is provided by a combination of a ROTRONIC HygroClip probe, an embedded Platinum Resistance Thermometer (PRT) and a multi-loop controller. Set-points are entered using the touch-screen front panel display.

1.2 Temperature and Humidity References

The HygroGen2 creates stable temperature and humidity conditions uniformly within its test chamber. Instruments under test (IUTs) are inserted into the chamber and compared to a reference to calibrate and monitor their performance so that any appropriate adjustments can be made.

There are three main relative humidity (RH) calibration reference types that can be used with the HygroGen2. Each has its own advantages and disadvantages, so the reference chosen should be determined by the uncertainty of measurement required.

• Internal control RH probe reference

• External RH probe reference

• Chilled Mirror Hygrometer reference

Corresponding temperature references integrated in the above may be used or additional external temperature references employed (for example, platinum resistance thermometers (PRTs)). It is vital to consider the comparison of temperatures measured by the reference, the HygroGen2 and IUTs. Because RH is significantly dependent on temperature, temperature measurement should be optimised to get meaningful RH results.

For more details, please see A1: Calibration Reference Options and Appendices D1 to D4

Uncertainty.

1.3 Optional Enhanced Features: AutoCal, External Reference, Range

Extensions and Remote Control

With the introduction of software version 2.0, the HygroGen2 comes with optional Enhanced Feature upgrades: AutoCal and RH/Temperature Range Extensions. Version 2.1 has more additions to the Enhanced Features range: AutoCal+ and Remote Control. Further enhancements are in development and will be released in subsequent versions.

All Enhanced Features are activated by the application of a licence key, available via your ROTRONIC dealer, and can be added to any HygroGen2. Under certain circumstances a service may be required.

Low Temperature and Humidity Range Extensions extend the limits of points that can be set on the instrument, creating chamber conditions down to -5°C and from 2%rh up to 99%rh.

AutoCal allows you to pre-program a series of set-points and times, and record the instrument‘s progression through them in a PDF Calibration Certificate which is written to an external USB disk drive. Any values recorded on ROTRONIC HygroClip probes attached to the HygroGen2 via USB adaptors are recorded in the certificate. Probes can be set to automatically adjust to match the HygroGen2 reference probe at predetermined values.

AutoCal+ (External Reference) extends the functionality of AutoCal, by integrating MBW/RHS chilled mirror hygrometers (supplied separately) as the external reference.

Remote Control gives the ability to remotely control the HygroGen2 over a network. As part of this, there is a dial-back function so that ROTRONIC support personnel can log onto the instrument to offer support. Support is limited to the settings of the HG2-S, the unit may require a service that can only be carried out by trained personnel.

2 Setting up the HygroGen2

2.1 Physical Location

To ensure correct operation please ensure that:

1. The unit is level and stable;

2. There is at least 15mm clearance underneath and at least 100mm at the back of the unit to

enable adequate air flow;

3. There is adequate access to the electrical mains connection at the rear of the unit.

Note: The feet on the rear panel are for standing the unit for service purposes and to ensure a sufficient air gap behind the unit. The unit will not operate in the vertical position.

2.2 Electrical Supply

Power Isolation

The unit is supplied with a mains cord set. The unit should be disconnected from the electrical supply before the unit is moved, cleaned or has water added or removed.

Earthing

This unit must be earthed. Provision for the safety earth is made through the electrical mains connection (see Figure 2(8) below) to which all parts of the unit requiring earthing are internally connected. An earthed electrical supply is required.

Earth Leakage Current

Due to RF filtering, there is an earth leakage current, within the limits specified in EN 61010-1:2001. This may affect mains power circuits protected by Residual Current Device (RCD) or Ground Fault Detector (GFD) type circuit breakers (particularly if used in multiples or with other equipment with an earth leakage current on the same supply circuit).

Overcurrent Protection

To protect the internal circuitry against excess currents, the mains supply to the unit must be connected with the mains cord set provided with the unit and to an appropriate mains supply.

Voltage Rating

The unit is designed to work within the limits of a 110-230VAC 50-60Hz mains supply with voltage fluctuations up to ± 10% of the nominal voltage. The unit is rated impulse-withstand (overvoltage)

category II of IEC 60364-4-443. Where occasional voltage transients over 2.5kV are expected or measured, it may be necessary that the power installation to the unit includes a transient limiting device.

Mains Filtration

If there is risk of power spikes or breaks, it is recommended that an Uninterruptable Power Supply (UPS) is used to provide continued power and mains filtration. This should be rated according to the HygroGen2 power specifications (see Appendix B3

) and the time required to run/shut down during

power outage.

Conductive Pollution

The unit is rated Pollution Degree 2 and must not be operated in environments where conductive pollutants (for example, carbon) may enter the unit. This includes excessive moisture ingress.

2.4 Water Reservoir

The HygroGen2 requires 50-80ml of distilled water in the internal reservoir. Insufficient water will deactivate the humidification system. As long as extreme care is taken not to overfill the water reservoir, the HygroGen2 may be filled and emptied either with the unit powered up or shut down.

To fill the HygroGen2

1. Insert the tube of the dosing syringe, with the plunger fully depressed, 10mm into the water

port and extract any residual water by drawing out the plunger.

2. Depress the collar on the water port (Figure 1(4) above) and remove the dosing syringe tube.

Wipe up any spilt water with an absorbent cloth immediately.

3. Fill the dosing syringe with 80ml of distilled water. Insert the end of the dosing syringe tube

firmly back into the water port and discharge the syringe steadily. (If water leaks during this operation the filler tube is not correctly inserted in the water port.)

4. Depress the collar on the water port to remove the dosing syringe tube. Wipe up any spilt water

with an absorbent cloth immediately.

5. A water level indicator is shown in the Settings Screen (see section 3.4.5

Caution: Do not overfill the HygroGen2

Overfilling of the unit will result in poor humidification and, in extreme cases, water may be pumped into the chamber. If the HygroGen2 is overfilled, the humidifier should be fully emptied and then refilled with 50-80ml of water (as described above). If there is water present in the chamber of the HygroGen2, this should be removed using an absorbent cloth. Ensure the HygroGen2 is switched off and the mains power unplugged before manually drying the chamber.

To empty the HygroGen2

1. Insert the tube of the dosing syringe, with the plunger fully depressed, 10mm into the water

port and extract any water by drawing out the plunger.

2. Depress the collar on the water port to remove the dosing syringe tube. Wipe up any spilt water

with an absorbent cloth immediately.

3. Distilled water discharged from the HygroGen2 may be stored safely and reused at a later date.

Note: The HygroGen2 should always be emptied if it is being shipped or stored (see

section 5.3

Preparing the Unit for Transit or Storage). This will prevent ingress of water into the chamber should

the unit be inverted and prevent possible frost damage.

Water Quality

The HygroGen2 should only be filled with distilled water.

As a precaution against any microbial and algae water contamination, HygroGen2 incorporates an Ultra Violet (UV) sterilisation lamp within the water reservoir. No user intervention is required - HygroGen2 auto-cycles the process.

Under no circumstance should the water reservoir be opened by non-qualified personnel. Direct

exposure to UV lamps can cause burns or blindness.

When rebooted, please reselect “Network” via the “Settings” drop-down menu.

Plug the HygroGen2 into your network using a standard RJ45 Ethernet cable. If network functionality is not configured, “Network Status” will show as “down”. If it is configured, and assuming the network cable is attached to other networking hardware, it will show as “OK”, otherwise it will show as “unplugged”.

PLEASE note: if your instrument has serial number VCT-HG2-1280 or earlier and has NOT been serviced since January 2013, your instrument requires a physical modification. Please contact your ROTRONIC distributor who will arrange for this operation to be performed. Without this modification, the Network Status will show as “unplugged” even if it is plugged in correctly. Please also note, physical modifications made by anyone other than Authorised Service Centres will void the HygroGen2 warranty.

With the HygroGen2 plugged into a network, IP settings need to be configured. Networking addressing can be set to obtain an address automatically via DHCP, if your network supports it, or manually via “Static”. Please contact your local IT administrator for advice, if unsure. You may be required to advise the network hardware (MAC) address of the instrument. This can be found in the “HygroGen2 Info” via the “Support” drop-down menu.

The IP address assigned to your instrument will be reported in the Network Settings interface and via the “HygroGen2 Info” screen. The HygroGen2 will assign itself a network name/identity. This can be changed within the interface. It is recommended to change it to the instrument’s serial number, though local network policies may require something else.

Operation of the Remote Control functionality is described in section 4.3

3.3.2 Date and Time Settings

Date and time stamps are included in AutoCal and HW4 logged data.

To adjust these settings, select the “Date and Time” option from the “Settings” drop-down menu on the “Settings and Updates” screen.

3.3.3 Touch Screen Calibration

Should the touch screen calibration be significantly awry – which can happen when upgrading from version 1.x to version 2.0 – you can realign the touch screen calibration. You may wish to plug in a USB mouse to perform this step.

Select the “Touch Screen” option from the “Settings” drop-down menu on the “Settings and Updates” screen. Pressing the touch screen button will begin a four-point calibration. Press the cross in each corner of the screen as directed.

3.3.4 Activation of Enhanced Features

Enhanced Features can be activated via the “Upgrade Features” option on the “Updates” drop-down menu in Configuration Mode, or via the Settings screen in Standard Operation Mode. See section 4 more details.

Navigating to Other Screens (items 1, 10 & 14) The user can navigate to different screens using the drop-down menu (item 1) or can scroll through the

four main screens using items 10 & 11.

Setting Temperature and Humidity Set-Points (items 3 & 7) At any time, the user can change humidity or temperature set-points by simply touching the set-point on screen. A pop-up will appear and either the touch screen or, when connected, the keyboard/mouse may be used to input desired values.

Note: To aid a smooth and efficient transition between temperature set-points, the controller is programmed to suspend humidification during changes in temperature. Once the chamber temperature is within 0.7°C of the temperature set-point, the humidity control is activated.

When set-point combinations are programmed that resolve a low dew point condition (i.e. 0°C, 5%rh =

-36°C dew point), make sure that the desiccant is dry enough to achieve the desired value. Check the desiccant condition on the Settings screen (Figure 12) and consult maintenance records to establish when the desiccant was last changed. Stabilisation time to low RH conditions will be longer than normal as the chamber and internal surfaces need to be very dry.

Temperature and Humidity Control (items 5 & 9) The Temperature and humidity control can be set to automatic or off. Automatic mode results in the unit attempting to adjust to the temperature (or humidity) in the chamber to match the set-point value. When switched off the HygroGen2 does not control the parameter.

When off, the control buttons are grey. When on, but not stable, the control buttons are red. When on and stable, the control buttons are green.
