CALIBRATION
The scope iC227 does not have a certificate of cali-
bration, but this device has software and hardware de-
signed for auto time base calibration and calibration of
vertical gains and offsets on both channels. There is
also a software feature which allows manual calibra-
tion of the time base in case that the accuracy of the
internal crystal and auto calibration are not sufficient.
If the device is to be used in production where certified
calibration is required, then there must be done peri-
odically calibration against a known calibrated source.
Vertical offset calibration steps
1. Make sure that scope was powered on for mini-
mum 10 minutes
2. Open Calibration - Edit Calibration Data
3. Press the ”Set for Cal L” button and follow the in-
structions
Vertical offset
The ”Vertical Offset” calibration process allows writing
4 offset calibration variables to the device flash mem-
ory. This will adjust the channel trace to be at the level
of the channel pointer ”CH1>” and ”CH2>” seen on
the left side of the screen when the input voltage is
0.00 V. There are 2 calibration registers for each chan-
nel: 500 mV/div and 50 mV/div. The first one is respon-
sible for the vertical resolutions 1 V-0.5 V-0.2 V, while
the second represents 100 mV-50 mV-20 mV-10 mV.
