Model K110 outputs 10mV per mA of measured current. To take advantage of the Model K100 high sensitivity, best results are obtained through 4-1/2 digit (or more) DMM with a relative zero func- tion. The Model K110 was designed to provide the operator with enhanced low current linearity and accuracy, but is limited to 450mA Peak current. The Model K100/K110 always outputs a signal proportional to the total current (AC+DC) in the conductor under test. This has proven to be the most versatile signal output format, and allows the user to isolate and measure DC and AC components of measured current separately, if so desired. Typical applications include 4 to 20mA loop measurements, auto-... -

• The Red LED indicates a momentary or continuous overload of the instrument. Readings taken while the Red LED is ON or FLASHING should be considered inaccurate. Momentary or continuous currents exceeding ± 4.7A for Model K100 and 470mA for Model K110, and dynamic currents with large step discontinuities will cause the red LED ShopAEMC www. .com 1.877.766.5412 Shop for AEMC products online at: to turn ON. -

Tips For Making Precise Measurements The Model K100/K110 is capable of making measurements of DC and low frequency currents over a wide range. Here are some key considerations for getting the most accuracy from your displaying instrument: • When using the Model K100/K110 with a meter, it is important to select the range that provides the best resolution. Failure to do this may result in measurement errors. The examples shown on the next page use an ordinary 3-1/2 digit DMM with the Models K100 and K110, to measure 16.7mA ShopAEMC www. .com 1.877.766.5412 Shop for AEMC products online at: DC/AC MicroProbe Models K100 and K110... - Page 19 Resolution: 100µV Resolution: 10mV Display Error: 1.8% Display Error: 0% Display Error: 0% PUSH PUSH PUSH DC Zero DC Zero DC Zero 16.7mA ShopAEMC www. .com 1.877.766.5412 Shop for AEMC products online at: Figure 15 DC/AC MicroProbe Models K100 and K110...

• Always zero the Model K100/K110 prior to making a measure- ment. See §4.1 for procedure. • Make sure that probe jaw mating surfaces are free of dust and contamination. Contaminants cause air gaps between sensor halves, making the Model K100/K110 susceptible to external magnetic fields which can contribute to measurement errors. See... -
Page 21: Residual Readings Following Severe Overloads
Large short-circuit and transient currents outside the operating range of the Model K100/K110 may cause large residual readings. In extreme cases, the Model K100/K110 will not zero. If this happens: • Remove the probe from the test conductor. • Open the probe and release, allowing the jaws to snap back. Repeat this step several times. • Rezero the instrument before making successive measurements.

Page 22: Maintenance
• To avoid electrical shock and/or damage to the instrument, do not get water or other foreign agents into the case. Turn the Model K100/K110 OFF and disconnect the unit from all circuits before opening the case. Battery Installation Your Model K100/K110 has been shipped with a new 9V battery installed. To replace the battery: • Remove probe from any conductor and place it away from any active conductors, circuitry, etc. • Unplug electronic module from display device (e.g. DMM, oscilloscope). • Remove the screws from the bottom cover of the electronic module. • Replace battery with a new 9V alkaline type. • Replace bottom cover and re-attach with screws.

Page 23: Cleaning
To ensure optimum performance, it is important to keep the probe jaw mating surfaces clean at all times. Failure to do so may result in increased earth’s field susceptibility and overall errors in readings. The following is the recommended procedure for cleaning the probe sensor: (1) Apply a few drops of isopropyl alcohol to an ordinary sheet of white photocopy paper. (2) Open probe to expose the mating surfaces of the sensor and insert the sheet of paper into the jaws. Allow the jaws to close. (3) With the jaws closed, pull free the end of the paper through the jaws until it releases. (4) Repeat step (3) several times, using a new (dry) section of paper each time. (5) Open probe and inspect mating surfaces. They should be free of dust particles or any other contamination. Otherwise, repeat the cleaning process starting again at step (1).
