Step 4. Use the softkeys or numeric entry keys to enter the test signal level. When 
data is entered with the numeric entry keys, the softkeys change to units 
labels (mV, V, uA, mA, A).
Softkey Function
INCR ++ Increases the oscillator’s output level with a resolution shown in 
Table 3-14 or Table 3-15.
INCR + Increases the oscillator’s output level with a resolution shown in 
Table 3-10 to Table 3-13.
DECR - Decreases the oscillator’s output level with a resolution shown in 
Table 3-10 to Table 3-13.
DECR -- Decreases the oscillator’s output level with a resolution shown in 
Table 3-14 or Table 3-15.
