YourRH95 systemincludes a small humiditychamberthat can be usedto testyoursamples at ambient temperature.Toconnectthe RH95

controller to the supplied humiditychamberfollowthe below procedure:

Note:This chamberis alsousedwhenvalidatingthe humidity reading.

IMPORTANTNOTICE:The humiditysensor isextremelysensitive tocontaminants-DONOTtouch the exposedchipor allowanythingto come into

contact with it. These sensorscannot be repairedifbrokenor contaminated, and are notcovered bywarranty.

1. Carefully remove the capprotectingthe humidity sensor.Donot touch the exposed chip on the humiditysensor.

2. Remove the lid ofthe humiditychamberusingthe providedtool, as shown:

3. Screw the sensorinto the chamber,beingvery careful not to damage the fragile sensor.

4. Connect the 9 pinconnectorfor the sensortothe port onthe backofthe RH95 marked 'HumiditySensor'

10 v1.1.1

5. Connect the humiditytube fromthe front ofthe RH95 to the port on the humiditychamberopposite the sensor,as shown:

Note:Do not connect the humiditytube tothe same side ofthe chamber as the sensor,as this will affect the readings.

6. Replace the lidofthe humidity chamber.You are nowreadyto control the humidity in the chamber.

Connectingthe RH95 to aLinkam HeatingStage

Ifyou have purchased a Linkamheatingstage with humiditycapabilityto gowithyourRH95 controller,follow these instructions to connect it:

IMPORTANTNOTICE:The humiditysensor isextremelysensitive tocontaminants-DONOTtouch the exposedchipor allowanythingto come into

contact with it. These sensorscannot be repairedifbrokenor contaminated, and are notcovered bywarranty.

1. Carefully remove the capprotectingthe humidity sensor.

2. Screw the humiditysensorintothe provided threadedhole in the Linkam heatingstage,beingverycareful not to touch the sensor.

3. Connect the 9 pinconnectorfor the sensortothe port onthe backofthe RH95 marked 'HumiditySensor'

v1.1.1

4. Connect the humiditytube fromthe front ofthe RH95 to the port on the Linkam stage,as shown:

5. Insert the gas valve insert into the gas valve on the opposingside ofthe stage tothe humidity feed.

6. You are nowreadytocontrol the humidityofyourLinkam stage.

12 v1.1.1

Usingthe RH95Controller

This sectiondescribes the operation ofthe RH95 control unit.

Filling the water bottle

Before the RH95can control the humidityofyoursample chamber, the water bottle must be filled.Itis important that onlydistilledwateris used in

the HumidityGenerator.

Step1:

Make sure the controlleris powered downandthat the transit screws have beenremovedfromthe base ofthe unit. Store these screws in the

providedholes on the backpanel ofthe unit.

Step2:

Unscrewthe bottle lid assemblyandremove from the bottle,beingcareful not todamage the heatingelement.

Step3:

Halffill the bottle to the level indicatedandcarefully re-attachthe lid assembly. Do not fill the bottle past the maximumlevel indicator.

13

v1.1.1

Step4:

Remove the magnetic front panel ofthe RH95

Step5:

Slide the bottle into the RH95 and tighten the lockingscrewuntil it is just tight.Donot overtightenthe screw.

Step6:

Replace the magnetic front panel ofthe RH95

Important Note:Before shippingthe RH95, the water bottle should be removed from the unit, drained and placed into the space provided inthe

packaging.The RH95 shouldnot be shippedwiththe waterbottle fitted.

14 v1.1.1

Desiccant conditioning

When the RH95 has not beenusedinsome time, the desiccant inthe controllerwill needdryingoutbefore use. Itis advised toperformthis

procedure whenthe goods are initiallyreceived.

Tapthe buttonand the followingscreen will appear:

tap the 'set'time display and a keypad screen will appear:

Enter the time required inhours,minutes andseconds and press enter, then push the start button to begin the conditioning.

NOTE:The suggesteddryingtime is 1:00:00 hour.

Setting the humidity level

Tap onthe humidityvalue onthe LCD displayofthe RH95 controller. This will bringupa number pad.Enter a humidity value ofbetween 10-90%and

press Ent.Press Ctoclearthe last digit.

Press the (start)button to begin controllingthe humidityinyourchamber.

15

v1.1.1

RH95 settings and configuration

To checkthe serial numbers and firmware information forthe humidity controllerand attachedsensor,tap the button atthe top ofthe screen,

and the followingscreen will appear:

RH95 status

Tapthe buttonin the settings screen to see a graphical displayofthe current status ofthe RH95, as below:

Tap the 'X'buttontoreturntothe previous screen.

Humiditysensordetails

The buttonaccesses the humiditysensorinformation. This includes the chambertype it is designed forandthe serial number ofthe sensor.

Touchscreen Calibration

Ifthe touchscreen interface on the RH95 is not respondingcorrectlytotouch input,it may need to be re-calibrated. In order to do this, please follow

this procedure:

1. Power down the RH95 Controller.

2. Place a fingeronthe touchscreenandholdit there

3. While continuingto hold a finger on the screen, power the RH95 back on, you shouldsee the below screen:

(youcan now remove the finger fromthe screen)

4. Touch the blue dotinthe centre ofeachsmallwhite square. Once all 4 corners have been touched the RH95 will start normally.

NOTE:Use a biroorstylus tocomplete this operation, touches with a finger maynot be sufficientlyaccurate.

16 v1.1.1

Validatingthe humidityreading

Ifyou have purchased an optional Rotroniccalibrationstandard with your RH95 unit, you can use these to validate the humidity readingofyour

RH95.

Youshould have received the followingpackage:

This will containsome textile pads and five ampoules ofcalibration salts. The RH%will dependupon whichkit was ordered. Theyare available in RH

values of10%,35%,65%and80%.

These standards consist ofsalts which will alter the humidityofa small enclosedspace toa specific RHvalue,byeither absorbingor releasing

moisture into the air. The humidityreadings canbe affected by several factors,so the environmentmust be controlledwhenusingthese validation

standards:

·

Roomtemperature must be 23°C+/-2°C.

·

The humiditystandard must be atthe same temperature as the humiditysensor. A1 degree difference in temperature cancause anerrorof

up to6%RH

·

There mustbe no draughts in the calibration room

·

Do notexpose the calibration chamber to directsunlightwhile in use

·

Do notexpose the calibration salts todirect sunlight atany time.

Usage directions

Note:It is recommended thatyouwearsafetygoggles while performingthis validationprocedure.

1. Remove the lid ofthe supplied humiditychamberand place one ofthe textile pads inthe recess.

Note:do not touchthe textile pad with bare hands,as this cancause contaminationand inaccurate readings.Wearsterile gloves, oruse a clean

pairofpliers or tweezers to loadthe pad.

17

v1.1.1

2. Holdthe ampoule ofthe selected humiditystandardat the neckand bringthe entire contents intothe further,lower partofthe ampoule by

swingingor lightlytappingagainst the glass.

3. Breakthe ampoule at the marked place and emptyitcompletely onthe centerofthe textile padwhile tappingitlightlytomake sure all of

the liquidis soakedintothe pad.

Note:wrapthe topofthe ampoule with tissue paper to containanyglass fragments.

4. Screw the humiditysensorintothe chamber.

Note:Be careful duringthis step to make sure the RH sensordoes not come into contact with the soaked pad. The salts will damage the sensorifit

comes intocontact with them.

18 v1.1.1

5. Replace the lidofthe humidity chamber and place the caps on the white plastic airports.

6. Allowthe chambertoreach humidityequilibrium (see table below)andswitch the RH95 uniton. You can nowcompare the humidityreading

ofthe RH95 with the expectedhumidity value ofthe calibration standard used to validate the accuracyofthe RH95.

Note:After everycalibrationthe textile pad must be renewed and the chamber washed out with waterandwell dried. Thoroughlywash yourhands

to remove anytraces ofthe calibration salts.
