  • Page 17 Measuring AC Amperage CAUTION! Do not attempt to make a current measurement with the test leads. The 265 measures the current by clamping the jaw around one conductor (wire). Clamping around more than one wire will result in erroneous readings. Make sure the temperature probe is NOT plugged in during this test.

  • Page 19 Measuring Diodes WARNING! Do not attempt to make diode measurements with the circuit energized. For accurate tests, remove the diode completely from the circuit prior to measuring it. Make sure the tempera- ture probe is NOT plugged in during this test. Instrument set-up: FUNC.
  • Page 20 Measuring Capacitance WARNING! All capacitance measurements are to be made on de-energized circuits with all capacitors discharged only. Failure to de-energize and discharge capacitors prior to measuring them could result in instrument damage and/or personal injury. Make sure the temper- ature probe is NOT plugged in during this test.
  • Page 21 Measuring Frequency WARNING! Never attempt a frequency measurement with a voltage source greater than 500V. Determine the voltage of any unknown fre- quency source before connecting the instrument in frequency mode. Make sure the temperature probe is NOT plugged in during this test.
