10 0 1-10 Hz
10 1 10-100 Hz
10 2 100-1000 Hz
10 3 1 kHz - 10 kHz
10 4 10 kHz - 100 kHz
10 5 100 kHz - 1 MHz
Generator Range
1. Set Multiplier to 10 5 and set Sweep for 1
µ
S. Adjust R9 for 1 Hz/Div.
2. Switch Multiplier to 10 4 and set Sweep for 10
µ
S. Adjust R8 for 1 Hz/Div.
3. Switch Multiplier to 10 3 and set Sweep for .1 mS. Adjust R7 for 1 Hz/Div.
4. Switch Multiplier to 10 2 and set Sweep for 1 mS. Adjust R6 for 1 Hz/Div.
5. Switch Multiplier to 10 1 and set Sweep for 10 mS. Adjust R5 for 1 Hz/Div.
6. Switch Multiplier to 10 0 and leave Sweep at 10 mS. Adjust R4 so 1 Hz spans
the entire screen (all 10 divisions).*
7. Set Frequency control to 1 (CCW).
8. Switch Multiplier back to 10 2 and leave Sweep at 10 mS. Adjust R10 for 1
Hz/Div.
* Note 1 Hz might span longer than 10 divisions due to component tolerance. To
compromise for this tolerance, adjust for greater than one division cycle when
adjusting trimpot R10 so the frequency ranges will overlapped.
This concludes calibration. If your generator fails to calibrate properly on one or
more Multiplier settings, check component values in the affected range(s) for
errors.
To complete your unit, install the the front panel (with the pc board attached) to
the plastic enclosure. Use the four (4) remaining 6-32 screws to secure the front
panel to the enclosure. Finally, place the four (4) rubber feet on the botton of the
enclosure. Place one at each corner.
