(2) The second and third section of calibration is same as the first section.
5.20.7 Counter Offset Calibration
Press 〖Count Cal〗softkey to enter into counter offset calibration window. Test the TP49
point on mainboard by using of DC multimeter. Then adjust the calibration value to make
the voltage on 0# of point TP49 as 0.5Vdc. Finally press 〖Finish〗key to exit the
calibration. (Please note that this calibration needs to open the case, if counter works
normal, you don’t have to calibrate it).
5.20.8 Trigger Level Calibration
Press〖Trig Level Cal〗softkey to enter into trigger level calibration window. Test the TP55
point on mainboard by using of DC multimeter. Then adjust the calibration value to make
the TP55 voltage on 0# as 0Vdc and on 1# as 0.5Vdc. Finally press 〖Finish〗key to exit
the calibration. (Please note that this calibration needs to open the case, if counter works
normal, you don’t have to calibrate it).
5.20.9 Store Calibration Value
User must store the calibration value after finishing the calibration, for it would be lost
once power-off. Press〖Cal Store〗key to save the data to non-volatile memory. Generator
exit the calibration after storage.
5.20.10 Recall Calibration Value
Press〖Cal Recall〗softkey then screen prompts inquiry “Back to factory calibration
setting?”. Press〖Default〗to select default calibration data. Press〖Finish〗to enable the
recalling. Press〖Cancel〗to exit the recalling.
When power on, the waveform generator will recall automatically the value from〖User
Value〗memory and applied to it.
5.20.11 Exit Calibration
If you select the other mode during the calibration process, the instrument will remain the
state of last calibration. If the state is not you want, press〖Exit〗softkey, the waveform
generator will resume the state of power on.
5.21 System Reset
Press 【Utility】key then to 〖Reset〗softkey to recall the default setting value.
5.22 Default Setting
