The HygrLab C1 is primarily designed fr measuring the water activity (Aw) f fds, pharmaceuticals and csmetics. The HygrLab C1 can als be used in ther labratry applicatins that require measuring humidity and temperature. The HygrLab C1 is equipped with a digital interface. Depending n the ptin the HygrLab C1 has either a USB r an Ethernet interface r with bth. The HygrLab C1 features tw distinct perating mdes: Aw Measurement: This specialized mde is used fr measuring the water activity (Aw) f prduct samples and materials in bulk such as pwders, seeds, etc. When set t perate in the water activity mde, the HygrLab C1 autmatically displays humidity as Aw (1.000 a w = 100 %RH). The Aw Mde ffers the fllwing ptins: Accelerated water activity measurement (AwQuick): permits measuring the water activity f mst prducts in typically 5 minutes. The measurement starts simultaneusly fr all fur prbe inputs and is ended autmatically. Cnventinal water activity measurement (AwE): the measurement starts simultaneusly fr all fur prbe inputs. The HygrLab C1 autmatically detects full equilibrium cnditins and ends the measurement at that time. The HygrLab autmatically signals the end f each water activity measurement and ffers the ptin f autmatically capturing bth the end result and the value f temperature in 4 separate data bins (ne nnvlatile memry per prbe). Up t 500 recrds can be captured per prbe and each recrd is stamped fr date and time. Data viewing can be dne frm the keypad and the data can be saved t a PC using the Rtrnic HW4 sftware. Standard Mde: in this mde the HygrLab C1 can be used as a general purpse indicatr with the fllwing functins: Relative humidity and temperature data measured by up t 4 HygrClip 2 digital prbes Calculated humidity parameter such as dew / frst pint r ther, fr up t 4 HygrClip 2 prbes Up t 4 user defined calculatins such as the difference between the temperature and the dew pint measured by a prbe, the average f the temperature measured by tw prbes, etc. The HygrLab C1 is available with a wide assrtment f HygrClip 2 humidity-temperature prbes t meet almst any requirement. The HygrClip 2 prbes feature well prven, durable sensrs. Digital signal prcessing ensures cnsistent prduct perfrmance and als facilitates the task f field maintenance with features such as ptentimeter free digital calibratin. 2011; Rtrnic AG E-M-HyLabC1-V1_10

See dcument E-M-TCPIP-Cnf available frm ur website. 3.7 Practical advice fr measuring humidity The mst cmmn surce f errr when measuring relative humidity is a difference between the temperature f the prbe and the temperature f the envirnment. At a humidity cnditin f 50 %RH, a temperature difference f 1 C (1.8 F) typically results in an errr f 3 %RH n relative humidity. It is always gd practice t mnitr the display fr temperature stability. The prbe shuld be given sufficient time t equilibrate with the envirnment t be measured. The larger the initial temperature difference between the prbe and the envirnment t be measured, the mre time temperature equilibratin requires. This time can be shrtened, and errrs avided, by using the prbe cnfiguratin that fits best fr yur applicatin. In extreme situatins, cndensatin may ccur n the sensrs when the prbe is clder than the envirnment. As lng as the humidity / temperature limits f the humidity sensr are nt exceeded, cndensatin des nt alter the calibratin f the sensr. Hwever, the sensr has t dry ut befre it can prvide a valid measurement. Nn-mving air is an excellent insulatr. When there is n air mvement, surprising differences in temperature and humidity can nted ver shrt distances. Air mvement at the prbe generally results in measurements that are bth faster and mre accurate. 4 Aw Measurement When enabled t measure water activity, the HygrLab C1 autmatically displays humidity as Aw (1.000 a w = 100 %RH) and ffers the fllwing ptins: AwE mde: the HygrLab C1 waits fr the full equilibratin f the measured prduct and prbe. Fr mst prducts, this takes frm 30 t 60 minutes. The HygrLab C1 autmatically detects equilibrium cnditins (humidity and temperature) and ends the measurement at that time by freezing the display. AwQuick mde: the HygrLab C1 uses an algrithm t accelerate the water activity measurement and prvides a result in typically 5 minutes. The measurement ends autmatically and the display is frzen. When temperature cnditins are stable (bth at the prduct and prbe), the value measured with the AwQuick mde is generally within ± aw f the value that wuld be btained by waiting fr full equilibratin f the prduct and prbe. NOTE: See technical paper E-T-AW (Measuring Water Activity) fr basic infrmatin n water activity and its applicatins. 4.1 Enabling Aw Measurement T enable the HygrLab C1 t measure water activity: Press the MENU key and select Aw Settings. Press ENTER t activate the menu. With the Enable Aw menu item highlighted, press ENTER and use the UP r DOWN arrw key t select ON. Press ENTER t cnfirm the selectin. Optinal: Use the DOWN arrw key t select the SaveResult menu item and press ENTER. Use the UP r DOWN arrw key t select either ON r OFF.

Recmmended value: 3 r 4 minutes. AWQ-Temp AwQuick The HygrLab C1 cnsiders temperature t be stable when the rate f change f the temperature signal is less than the specified value. Recmmended value: 0.01 C / min AWE-Temp AwE The HygrLab C1 cnsiders temperature t be at equilibrium when the rate f change f the temperature signal is less than the specified value. Recmmended value: 0.01 C / min AWE-Humi AwE The HygrLab C1 cnsiders humidity t be at equilibrium when the rate f change f the humidity signal is less than the specified value. SaveResult AwQuick AwE Recmmended value: Aw / min When the Aw measurement is ended, the result is saved in the fllwing data bins: Prbe 1: Bin 1, Prbe 2: Bin 2, Prbe 3: Bin 3, Prbe 4: Bin Aw prbe usage guidelines 1) HC2-AW prbe: check that the red LED n tp f the prbe is lit. This indicates that the prbe is being pwered. If necessary, pwer the prbe by pressing nce n the red buttn lcated n tp f the prbe. When the red LED is nt lit, the HC2-AW prbe is nt pwered and the instrument is nt receiving a signal frm the prbe. 2) Measuring with less than 4 prbes: bth the AwQuick and AwE functins run simultaneusly fr all HygrLab C1 prbe inputs. We strngly recmmend t either discnnect r t pwer dwn any unused prbe. IMPORTANT: The measurement starts simultaneusly fr all prbe inputs (discnnect r pwer ff any unused prbe) Usually, the measurement ends at a different time fr each prbe. When using multiple prbes, the HygrLab C1 emits a shrt beep whenever a prbe is dne measuring. A lng beep indicates that the last prbe is dne. When Data Strage is enabled, the end result f each prbe end result is stred in memry (bins 1 t 4) Each prbe can be displayed by using the UP r the DOWN key Pressing ENTER resets all prbe inputs and discards any measurement result that has nt been stred. 2011; Rtrnic AG E-M-HyLabC1-V1_10

14 Dcument cde HygrLab C1 bench-tp indicatr: Dcument title Rtrnic AG Bassersdrf, Switzerland Page 14 f 28 Instructin Manual Dcument Type 4.4 Using the AwQuick mde The HygrLab C1 uses an algrithm t prject the full equilibrium value (water activity) f the prduct sample: 1) The value f the humidity signal is cnstantly mnitred 2) The stability f the temperature signal is cnstantly mnitred 3) After an initial perid f time (dwell time), the humidity data is used t prject the end value f the equilibratin prcess (water activity). The measurement ends autmatically as sn as the prjected Aw value is stable. At that time, the HygrLab C1 freezes the display. The measurement is autmatically ended and typically requires abut 5 t 6 minutes. With the default dwell time f 4 minutes, the difference between the AwQuick functin and the cnventinal measurement methd is typically aw r less. The value f the dwell time can be set by the user (see SETTINGS) and is a tradeff between speed f measurement and accuracy. Generally, a lnger dwell time prduces mre accurate results but causes measurements t take lnger. The value f temperature shwn at the end f the measurement is the average temperature during the measurement. The HygrLab C1 displays a trend indicatr t the left f the temperature value. This is used t verify that temperature was stable during the measurement. 1.
