E1x052: TEC comparator test failed (a, b, c, d)
Checks the TEC regulation voltage comparator
a shows the 10bit ADC reading for the high output voltage
b shows the 10bit ADC reading for the low output voltage
c shows the lower limit
d shows the upper limit
x refers to the module channel tested
Please return the unit to your local service center for repair
E1x053: TEC default temp invalid (a)
Verifies whether the default temperature is within a given range
a shows the default temperature
x refers to the module channel tested
Please return the unit to your local service center for repair
E1x054: TEC control failed (a, b, c)
When the TEC is enabled the temperature must move towards
the default temperature, coming from a previous temperature be-
fore the TEC was enabled. The moving direction must be correct
and the overshoot must be less than a certain limit
a shows the temperature before the TEC was enabled
b shows the actual temperature while TEC is enabled
c shows the target temperature, where b should move to
x refers to the module channel tested
Please return the unit to your local service center for repair
E1x060: 0.25V offset failed (a, b)
Verifies that the offset voltage for the 16-bit ADC (250 mv) is cor-
rectly added to the input signal
a shows the ADC reading
b shows the maximum difference to the exact ADC reading
of 3277
x refers to the module channel tested
Please return the unit to your local service center for repair
