Wherever current flows, you have to be able to measure it; that's part of repairing electronically controlled cameras.
Voltage and resistance are the most commonly measured quantities for direct current, as found in camera circuits. Continuity also provides information as to whether, for example, a contact is conducting or blocking current. This is what a multimeter does.
If there are voltages that change over time, such as square-wave signals in digital circuits, you need an oscilloscope to make the voltage changes visible.
The device shown can do both and is also small and handy. Ideal for a small camera workshop where space is at a premium.
Today I tested the oscilloscope part with the frequency generator shown above in the picture.
Of the 1000 functions, I only need one for my purposes: the automatic display of signals as they are present at test points in the circuits. By comparing this with a reference, you can determine whether this part of the circuit is functioning correctly.
The device allows measurements in the low-frequency and high-frequency range up to 20 MHz to be performed on two channels. Sufficient for my 1980s SLRs.
