ECE132L – INSTRUMENTATION AND CONTROL LABORATOTYÒ
LABORATORY ACTIVITY #1
base unit/DC fundamentals circuit/DC Ammeter
Name: John Raymond A. Alla
Date: January 27, 2018
Laboratory Instructor: W.A. Deveza
The Manual Base
Unit contains a total of 32 Circuit Modification (CM) and fault switches.
Students manually select CM switches as the course progresses, while the
protected fault switches are reserved for Instructor use by means of an integrated,
The FACET base
units provide voltage supply with protection and conditioning circuitry to run
each FACET board
The DC FUNDAMENTALS
circuit board connects to the base unit with the ZIF connector.
A CW rotation
opens the ZIF connector: a CCW rotation locks the ZIF connector.
To verify the
operation of the + 1OV control on the base unit, you can measure the variable power source on the OHM’S LAW
circuit block of the DC FUNDAMENTALS

to a circuit by placing a two-post connector between the energizing test points in the circuit.
A basic 1 mA
full-scale meter movement can be used as an ammeter.
You can use
a shunt resistor to extend the range of a 1 mA meter movement to indicate a 10 mA full-scale circuit
