Measuring AC Amperage Measuring Resistance WARNING! Do not attempt to make resistance measurements with circuit energized. For best results, remove the resistor completely from circuit before attempting to measure it. Make sure the temperature probe is NOT plugged in during this test. NOTE: To make accurate low ohm measurements, short the ends of the test leads together and press the REL button to store the reading.

Measuring Capacitance Measuring Frequency WARNING! 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 temperature probe is NOT plugged in during this test. Never attempt a frequency measurement with a voltage source greater than 500V.

E. Other Features Manual Ranging (RANGE) The range hold button (RANGE) activates manual ranging. Press the RANGE button to cycle through available ranges. Pressing and holding the RANGE button for approximately two seconds returns the meter to autorange mode and “auto” will be displayed in the upper left corner of the display. Data Hold (HOLD) Press the HOLD button at any time to freeze the reading on the LCD display.

Application Notes (DC Volts) Application Notes (Resistance) The 265 will accurately measure rectified DC Voltages like those encountered in furnaces and other appliances even though many of these devices do not have output filtering or other signal conditioning. When measuring DC Voltage of a battery, the most accurate reading can be attained by testing the battery under load.

Application Notes (AC Amps) G. Trouble Shooting When measuring AC Amps of a motor there are two types of measurements that can be made, running current and in-rush or start-up current. Start-up current will usually be much higher than running current.
