error message E1x062: PGA gain adj failed (a, b, c)
description Verifies the gain settings of the PGA (x 1/10/100). A voltage of 25 mV is applied to the
input of the PGA and then amplified
test value a if 1, the required division has failed
if 0, the calculated factors are correct
b shows the measured values for an amplification by 10
c shows the measured values for an amplification by 100
d shows the quotient of b divided by c
x refers to the module channel tested
action Please return the unit to your local service center for repair
error message E1x063: Lambda DAC adj failed (a, b, c, d)
description Verifies the gain of the responsiveness correction stage
test value a if 1, the quotient d could not be calculated, otherwise 0
b shows the difference between DAC settings 1024 and 2048
c shows the difference between DAC settings 2048 and 4096
d shows the quotient of b divided by c
x refers to the module channel tested
action Please return the unit to your local service center for repair
