Falling load mA waveforms are illustrated below. Turn the WINDOW DELAY control to display
more than 50 msec in the MSEC display.

In the example above, set T, the window delay, to 200 mS. This enables measurement of the
second step of the above waveform. If a scope is not available, make a series of exposures and
record kV/mA as a function of delay time.
The user should be cautioned that the mAs displayed is not the mAs of the entire exposure, but
only the mAs of that small section. The mA is averaged over a 20 msec interval and is derived
using the formula:
mA =
mAs
0.02
Other suggested applications are studies of automatic filament/mA control systems where it may
be desired to measure the mA during the first pulse and at some time thereafter, in which case turn
the WINDOW DELAY control OFF, make an exposure and record the data. The window position
