3. When the display shows the desired excitation, press the Enter Key to save the value in memory. The
display acknowledges the selection and returns to:

4. Press an Arrow Key to scroll to another menu or press the Gross or net Key to return to Run Mode.
62 reSoluTIon
This function controls effective resolution by changing the conversion rate of the 21-bit A/D converter. In general,
the higher the resolution, the slower the conversion time, but the greater the stability. The table below shows the
effective resolution and associated conversion times. The default is 21 bit.
Effective Resolution (bits) Conversion Time (mS)
16 17
17 20
18 25
19 34
20 50
21 100
Follow this procedure to adjust the effective resolution:
1. If the SVS2000 is in Run Mode, press the ‘6’ Key, ‘2’ Key, and Enter Key to access the menu tree. The
display shows:
62 reSOLuTIOn
2. Press the enter key to access this menu. The display looks like this:
reSOLuTIOn:*21bt
(Asterisk indicates the current selection.)
If the displayed menu does not have the desired resolution, press the Up Arrow Key to display the next
page of the menu. Continue to press an Arrow Key until you see the desired resolution (there are six
pages to the Resolution Menu).
3. When the display shows the desired selection, press the Enter Key. The display acknowledges the
selection and returns to:
62 reSOLuTIOn
4. Press an Arrow Key to scroll to another menu or press the Gross or net Key to return to Run Mode.
63 SenSor gaIn
Adjusting the gain increases or decreases system sensitivity. The type of sensors connected to the SVS2000
determines the required gain. For example, for a nominal excitation output of 12 volts, the reference voltage is
one quarter of the excitation voltage, or 3 volts. At a gain of 1, the A/D converter spreads 2,097,152 counts over
a range of ± 3 volts. A gain of 2 spreads the counts over a range of ± 1.5 volts, doubling the sensitivity. A gain of
4 spreads the counts over a range of ± 0.75 volts, doubling the sensitivity again, etc.
The SvS2000 set the gain based on your entries in Quick Config:
