DC/AC MicroProbe Models K100 and K110 11CHAPTER 4OPERATION4.1 Making Measurements with the K100/K110• Remove any conductor from within the probe jaws.• Plug the electronic module into the displaying device (e.g., DMM, oscil-loscope). Note the polarity of the module output banana plugs (red =positive [+], black = negative [-]).• Select the appropriate range on displaying device (e.g., DMM, oscil-loscope). Note that the module output is 1mV/mA for Model K100 and10mV/A for model K110.• Turn displaying device power ON. Turn on the Model K100/K110 (thegreen LED should be ON, and the red LED OFF).• With the probe disconnected from test samples (no conductor in probejaw window), adjust the zero control (push in the knob and turn) toread zero volts on the displaying device. In the unlikely event wherethe zero point is unobtainable, refer to Residual Readings FollowingSevere Overloads (§ 4.6) - the Model K100/K110 probe may be tem-porarily magnetized.• Clamp the probe around the conductor to be tested. The displayingdevice should now display the measured conductor current. In DC, apositive reading indicates current flowing in the direction of the arrowon the probe. A negative reading indicates current flow in the oppositedirection of the arrow.4.2 Indicator Lights - Green and Red LEDs• The Green LED indicates that the Model K100/K110 is ON and that thebattery is good. The Green LED will not light under low battery condi-tions. Replace the 9V battery if the green LED is not lit.• The Red LED indicates a momentary or continuous overload of theinstrument. Readings taken while the Red LED is ON or FLASHINGshould be considered inaccurate. Momentary or continuous currentsexceeding ± 4.7A for Model K100 and 470mA for Model K110, anddynamic currents with large step discontinuities will cause the red LEDto turn ON.www.ShopAEMC.comShop for AEMC products online at: 1.877.766.5412
