Final answer:
A multimeter and an oscilloscope can be used to troubleshoot programmable timers by measuring voltage and visualizing electrical signals.
Step-by-step explanation:
A multimeter and an oscilloscope can be a tremendous aid when troubleshooting programmable timers.
A multimeter is a versatile tool that measures voltage, current, and resistance. It can be used to check if the power supply to the timer is functioning properly, and to measure voltages at different points in the circuit to identify any abnormalities.
An oscilloscope, on the other hand, is used to visualize electrical signals. It can help analyze the waveforms of the voltage pulses generated by the timer, which can provide valuable insights into any timing issues or irregularities.
