Controls & Indicators
The FE160 Senior Field Effect Meter has two front-panel controls: the OHMS ADJ and the ZERO ADJ. The RANGE SWITCH is a push button used to select the desired range.
Installation / Setup
Refer to the PDF for details.
Operation
The FE160 Senior Hi-Lo Field Effect Meter is equipped with a shielded test lead and probe for accurate AC voltage measurements in the presence of strong electronic and magnetic fields. The probe connects to the FE160 with a BNC type connector and includes a 100K isolation resistor and switch to isolate cable capacity in critical circuits. The probe switch is typically left in the NORM position for most measurements, including DC voltages. The ISOLATION position is used to isolate cable capacity or when using the LO power ohms function in specific circuits. The ISOLATION position should only be used for DC voltage measurements and AC voltages at no more than 60 Hertz to avoid errors.
The FE160 is simple to operate. Users depress the desired function on the Function switch, select the desired range on the Range switch, and measure. The front panel includes two additional controls: the OHMS ADJ and the ZERO ADJ. The range switch is a push button used to select the measurement range.

Safety & Warnings
When testing electronic equipment, there are several safety precautions to observe:
1. Always use an isolation transformer on equipment with the chassis tied to one side of the AC power line.
2. Remove power before making test lead connections to high voltage points. If this is not possible, avoid contact with other equipment or metal objects, keep one hand in your pocket, and stand on an insulated floor to reduce shock risk.
3. Discharge filter capacitors before connecting test leads, as they can store a dangerous charge.
4. Ensure equipment is in good condition; broken or frayed test leads can expose the technician to dangerous potentials.
5. Remove test leads immediately after completing the test to reduce shock risk.
6. Do not work alone on hazardous circuits; always have someone nearby in case of an accident. Even minor shocks can lead to more serious accidents, such as falling against equipment or contacting higher voltages.
