7. Gain Calibration
The WFM 601i has both factory preset and user adjustable horizontal and vertical
gain calibration. To access GAIN CAL (you must be in the
CONFIGURE/CALIBRATE submenu) push the second from the bottom bezel
button and observe that the cursor box now surrounds the ON readout.
The other two assignable bezel controls are now labeled V CAL and H CAL.
Rotate both controls enough to see that the horizontal and vertical gains have
changed noticeably and that two new labels have appeared next to the bezel
buttons. They are RESET V CAL and RESET H CAL. See Figure 1-18.
Push the RESET V CAL button to return to the factory calibration setting. Note
that the vertical amplitude returns to 700 mV and that the RESET V CAL label
disappears.
Push the RESET H CAL and note that the horizontal gain returns to one cycle
per division and the RESET H CAL label disappears. Exit the configure menu
by pressing the CONFIG button. The calibrator signal is automatically turned
off.
