E1x061: PGA DAC adj failed (a, b, c)
Tries to adjust the offset voltage of the PGA
a shows the ADC Offset reading
b shows the limit for an upper offset
c shows the limit for a lower offset
x refers to the internal PM channel tested
Please return the unit to your local service center for repair
E1x062: PGA gain adj failed (a, b, c)
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
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
x refers to the internal PM channel tested
Please return the unit to your local service center for repair
E1x063: Lambda Dac adj failed (a, b, c, d)
Verifies the gain of the responsiveness correction stage
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 internal PM channel tested
Please return the unit to your local service center for repair
E10070: Laser <a> control failed (b, c)
Checks the laser current source
a laser number
b low power setting
c high power setting
Please return the unit to your local service center for repair
E10080: Laser <a> control for safety test failed
To test the current safety comparator the laser current needs to be
set to two different values
a laser number
