SLICEWare Gain Calculation

SLICEWare uses the three fields to determine the gain; proportional, sensitivity, and desired range. There is not a way to work around this as the setting is hard coded in SLICEWare. If you have a specific sensor or setting, please 'Submit a request' and the support staff can provide example settings. 

The easiest way to set the gain to a specific setting is to enter the following for the Forced Gain Setting in the spreadsheet:

• Proportional = No
• Sensitivity = 1.00
• Choose your gain from the available pull-down
• Enter the value of 'Range wo/headroom' in the prepare tab for the sensor settings to effectively force this gain
  • This gain setting is transparent to the user as the majority of users are not experienced to determine the best gain setting
  • Because of this automation of the software we must find a way around the hard coding of the software

The algorithm is based on an input range of the SLICE of 2490 mV (+/-2490 from a 2.5V center). The formula in SLICEWare is:

• Input range/sensitivity*5V excitation/headroom=max allowable gain
  • Input range=2490
  • Excitation used is 5.0 when proportional =YES and 1.0 when proportional = NO
  • Head room =1.2
• In the example below we have
  • 2490/1/129=max gain of 19.3 (SLICEWare chooses the next lowest available gain to eliminate clipping the signal). Or...
  • 2490/1/16/1.2=max range (with 20% headroom) of 129

The headroom setting is found in the SLICEWare.exe.config file:

<setting name="ConfigurationRangeHeadroomPercent" serializeAs="String">
<value>20</value>
</setting>
