I N T R O D U C T I O N The KAM Weight Scale is designed for integration with the KAM CSS Complete Sampling System and is used ® ® to verify sample volume in KAM SR Sample Receivers per API Chapter 8.2, ASTM 4177 and ISO 3171. Weight ® Scale units (generally 2) are placed inside a KAM SRH Sample Receiver Housing, and the KAM SR Sample ® ® Receivers are placed on top of the Weight Scale platforms. Each Weight Scale unit communicates with the KAM SC Sampler Controller via 4-20 mA. The 4-20 mA signal directly correlates to the current weight of the Sample Receiver and its volumetric equivalent. In this way, op- erators can remotely monitor for accumulated sample volume, and automatically switch to a second Sample Receiver for continued sample collection once the first receiver is full. - Page 4 MODELS AND SPECIFICATIONS 0-60 lbs (0-27 KG) Standard for use with a 3 gallon sample receiver Resolution: .02 lb (9 grams) Dimensions: 9.25"W x 9.25"D x 1.25"H (235 MM x 235 MM x 32 MM) Maximum weight: Recommended no more than 66 lbs (30 KG), max overload 90 lbs (41 KG) 0-100 lbs (0-27 KG) Standard for use with a 3 or 5 gallon sample receiver Resolution: .02 lb (9 grams) resolution...

Place Weight Scale(s) in Sample Receiver Housing FIG. 3-2 and adjust feet by screwing them in or out (Fig. 3-2) to ensure that the scale is complete stable and does not rock. 2. Mount Weight Scale Controller(s) within 6' – 8' (2 – 2.4 M) of housing. 3. Connect the Scale and the Scale Controller with Adjustable feet the supplied 10' wire using quick connects. WARNING: The KAM Weight Scale has mechanical stops to prevent damage from overweight receivers. HOWEVER, placing receivers above the maximum weight or slamming receivers down onto scale will result in damage to the scale. WIRING 1. Remove cover from Weight Scale Controller by first FIG. 3-3 removing set screw on the bottom of cover (see Fig. 3.3) and then turning cover counter clockwise. Set screw 2.

3. Connect the other end of serial cable to computer serial port or serial port converter. NOTE: In order to change settings in the control- ler, user must first select the communications port. While some menu options can be used without first selecting the port, in most cases it is simpler to do FIG. 4-2 so prior to using the software. 4. Open WSC software on computer. The initial screen will display the KAM logo. 5. Go to COMM on the top menu bar and select PARAMETERS. 6. A pop-up window titled "Serial Port Configuration: will appear. See Fig. 4.2. 7 . Under "Com port" select the appropriate port for your computer and click OK. You do not need to do anything with the other settings. Pop-up window will disappear. -
