R1-If ZERO count is less than 2000, put resistor at R1 to increase the ZERO count value.
R2- If ZERO count is more than 9000, put resistor on R2 to decrease the ZERO count value.
ZERO Count Adjustment Procedure:
1. ZERO count value is below the lower limit i.e. 2000.
• If there is any resistor at R2, please remove it.
• Check the zero count. If the ZERO Count value is between (2000~9000), stop the
procedure, ZERO Count value is successfully adjusted.
• If the count is still below 2000, use metal resistor 100K on the R1, then check the ZERO
count, if the count moves over 9000, change the resistor to 50K or below, until the zero
count comes under the ZERO Count range.
2. ZERO Count value is above the upper limit i.e. 9000.
• If the ZERO count is above 9000, use metal resistor 100K on the R2, then check the
zero count, if the count is still over 9000, change the resistor to 150K or above, until the
ZERO count comes under 9000 and between ZERO count range.
*After determining the required resistor, solder it
