This instrument can only be operated as a stand-alone system. No analysis programs for PC (Novalog MC) and no cable are included. -
Page 9: Optional Accessories
Novasina offers various protective filter systems for this purpose. Please consult the corresponding datasheets for Novasina protective filter systems or contact your Novasina sales partner. Using filter systems can prolong the service life of the measuring cell considerably. Should you implement such filter systems, please see to it that they are tested and changed at regular intervals. -

• Insert the power cable into the instrument socket and plug it into the mains. Switch the mains power on if necessary. • Switch on the LabMASTER-aw by the power switch on the front of the instrument (lower right corner). The display will light up. - Page 11 Note: The connector cable, with 1.8 m cable and corresponding plugs, comes with every LabPARTNER-aw.

An additional LabPARTNER-aw instrument may be placed directly beside Fault the LabMASTER-aw unit or up to the distance of the cables (1.8m) around it, wherever there is space available. Special systems with up to 9 additional channels may be distributed over different rack levels. - Page 13 A sample or a SAL-T can be inside but the speed of changing will be slower. Please wait during the temperature stabilisation process. Note : If you are using a multi-channel system (LabMASTER-aw and at least one LabPARTNER-aw), select the chamber number before changing the settings ! 3.4.5.
- Page 14 It will be possible to update an "BASIC" or "STANDARD" to the next possible version or directly to a "ADVANCED" version of a LabMASTER-aw. The way is very simple and code driven. A new code can be ordered through your local Novasina representative.
- Page 15 The system runs a comprehensive function control of all internal modules and important software components when starting up. After this, the LabMASTER-aw tries to establish a connection to any connected LabPARTNER-aw units. Any errors in the LabMASTER/ PARTNER-aw hardware or software are then shown in an information window on the LabMASTER-aw.
- Page 16 Elements of the configuration menu: You open the main menu by pushing the „Settings“ soft key. Selecting a further menu point (e.g. „3“) and then pressing the „ENTER“ (5) soft key brings you to the submenu and the corresponding display window. Pressing the „Previous screen“ soft key (6) brings you back one menu level.
- Page 17 (recalibration with SAL-T standards) With this function, every LabMASTER/PARTNER-aw can be periodically checked and, if necessary, recalibrated using the Novasina humidity standard, SAL-T, at various measuring points. For this purpose, a special box set with 6 SAL-T humidity standards is included with every LabMaster.

Currently the PC and Printer devices are defined. With the PC device, LabPartner units (1..9) can be connected parallel over the LabMASTER-aw, the main unit, to a PC that is running the "NovaLog MC" analysis software and thus data transmitted online. - Page 25 Only so you can be certain that the same functions will be available after repair. A label on the LabMASTER-aw gives information on the system code of the delivered unit. Please complete this if needed.

Displayed values The Novasina LabMASTER-aw continuously measures the water activity (a lected / %RH) and the temperature (°C/°F) and displays the momentary values with bigger letters on the screen. If an analysing of an probe will be finished, the Actual system will fix the result. - Page 27 Correct handling of the sensor Note : Before starting the measurement. The Novasina sensor is a highly sensitive precision device. Please observe the following rules in order to avoid measuring errors or even destruction of the sensor : •...
- Page 28 • Never open or take the measuring cell apart or clean the sensor with any chemical or mechanical parts! The sensor itself is not cleanable. All attempt will expire the warranty. • Under no circumstances connect the sensor to an Ohmmeter or such like. This may damage the sensor and will expire the warranty of the sensor! Any warranty will expire if one or more of these points counteracts !!
- Page 29 The temperature stability observation time may also be changed from the factor „5“ set by Novasina to a higher factor for products with a temperature greatly different from that of the chamber (e.g. chilled samples).
- Page 30 The "Sorptions isotherm" chart gives the depending of both factors. Such chart are valid and unique only for one type of probe. Novasina has created a special "SI" set. For such purposes using this set in combination with a LabMASTER / PARTNER-aw, you can record such "Sorpitons isotherm"...
- Page 31 Recording a Sorption Isotherm curve Setup the LabMASTER/PARTNER-aw The lower part of the probe chamber of a LabMASTER/PARTNER-aw must be prepared first. Change the standard steerage to the special steerage for SI set. Take a screwdriver No. 2 and replace the steerage (see pictures below).
- Page 32 Desorption curve This is in princple the inverse part of an adsorption curve. The substance must be more humid when starting to weigh (to be safely on the desorption curve to avoid SI-hysteresis mistakes), so the first salt to use is SAL-T97. Upon reaching a value well above 0.9, SAL-T90 can be placed in.
- Page 33 SAL-T into the measurement chamber Example of doing a Sorption Isotherm curve (adsorption) with a biscuit: • Selected temperature of Novasina instrument: 25.0°C. • The totally desiccated sample has a net weight of 0.485g. • SAL-T 11% was placed together with the sample in the chamber.
- Page 34 QC manual, or fix shorter recalibration periods according to personal standards. An other good way is, to test one point with a Novasina SAL-T standard that fit near to the last measurement point of the last few probes at the end of a day.
