Page 8: Capacitance Measurements
Capacitance Measurements WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any capacitance measurements. Remove the batteries and unplug the line cords. • Set the rotary function switch to the Ω CAP ) position. - Page 9 • For current measurements up to 6000μA AC, set the function switch to the yellow μA position and insert the red test lead banana plug into the μA/mA jack. • For current measurements up to 600mA AC, set the function switch to the yellow mA position and insert the red test lead banana plug into the μA/mA jack.
- Page 10 Capturing Minimum and Maximum Values The MAX MIN Record mode captures minimum and maximum input values. When the input goes below the recorded minimum value or above the recorded maximum value, the meter beeps and records the new value. This mode is for capturing intermittent readings, recording minimum and maximum readings unattended, or recording readings while equipment operation precludes watching the meter.
- Page 11 Thermal imager and DMM Operation Thermal imager basics In the Thermal imaging and DMM mode user can measure a targeted surface’s temperature and use Multimeter at the same time. The measured result will display under the thermal image. • Press the red “IR” button to open the Thermal Imager. In the image shown the thermal image is set to color palette IRON.
- Page 12 The display will show the temperature measurement in the upper left hand corner for the targeted area along with the currently selected emissivity value. In the Thermal imaging mode, the laser pointer and display cross hairs can be used to assist in targeting.
