Controls & Indicators

The front-panel controls and indicators for the Sencore FE14 and FE16 Field Effect Meters include the following:

– OFF-ON switch: Controls the power to the circuit. A red flag appears in the switch opening to indicate when the meter is on.
– ZERO ADJ: Used to position the pointer of the meter over the zero on the extreme left of the meter scale or on the center zero when using the zero center ranges.
– OHMS ADJ: Used to adjust for a full-scale deflection (zero ohms) on the ohms scale of the meter.
– FUNCTION SWITCH: Selects the type of measurement to be performed, such as DC Volts, AC Volts, Ohms, or Battery Check.
– RANGE SWITCH: Selects the desired range of current, voltage, or resistance to be measured.

Installation / Setup

Operation

The Sencore FE14 and FE16 Field Effect Meters are designed for ease of operation, similar to a standard VOM. They include controls such as the OFF-ON switch, ZERO ADJ, OHMS ADJ, FUNCTION switch, and RANGE switch. The OFF-ON switch controls the power, with a red flag indicating when the meter is on. ZERO ADJ positions the pointer for zero readings, while OHMS ADJ is used for full-scale deflection before measuring resistance. The FUNCTION switch selects the type of measurement, and the RANGE switch selects the measurement range.

For operation, set the FUNCTION switch to the desired test, the RANGE switch to the appropriate range, connect the leads, and read the results on the meter. For DC volts, set the FUNCTION switch to plus or minus DCV/MA, choose the range, connect the leads, and read the results. For AC volts, set the FUNCTION switch to ACV/OHMS, select the range, and use the appropriate scales for RMS or peak-to-peak voltages. Zero center scales allow reading of plus or minus voltages without changing polarity.

  • Compatible with a wide range of N-channel and P-channel FETs
  • Robust construction for durability in various working conditions

Basic Usage and Operation Tips

Before testing, ensure the meter is properly calibrated according to the manual instructions. Insert the FET leads into the designated test sockets, observing correct polarity. Use the meter’s controls to select the desired measurement mode. Allow the device a few moments to stabilize before reading the measurement. For best results, test components at room temperature and avoid touching the leads during measurement to prevent interference.

Troubleshooting and Maintenance

If the meter displays erratic readings or fails to power on, first check the battery condition and replace if necessary. Clean the test sockets regularly to maintain good contact with device leads. Avoid exposing the meter to moisture or extreme temperatures. If calibration drift is suspected, perform recalibration as outlined in the service manual. For persistent issues, consult the detailed troubleshooting section of the manual or contact authorized service personnel.

Safety Reminder

Always disconnect the meter from any circuit before testing to avoid electric shock or damage. Use the device only within its specified voltage and current limits. Handle the meter with care and store it in a dry, dust-free environment when not in use. Following these safety precautions will ensure accurate measurements and prolong the life of your Sencore Field Effect Meter.
