Example: hardwired equipment in fixed installation and circuit breakers. CAT II corresponds to measurements performed on circuits directly con- nected to the electrical distribution system. Example: measurements on household appliances and portable tools. DC/AC MicroProbe Models K100 and K110... -
Page 7: Precautions For Use
• Use caution on any circuit: Potentially high voltages and currents may be present and may pose a shock hazard. • Read the Safety Specifications section prior to using the Model K100/ K110. Never exceed the maximum voltage ratings given. -
Page 8: Product Features
The K110 has an operating range of 100µA to ± 450mA Peak, from DC to 1500Hz.* Models K100 and K110 are designed to be operated in conjunction with a digital multimeter, oscilloscope or recording device. The MicroProbe out- puts the current measured in the form of a voltage that is the image of the current, in shape and amplitude. -

Page 14: Operation
Readings taken while the Red LED is ON or FLASHING should be considered inaccurate. Momentary or continuous currents exceeding ± 4.7 A for Model K100 and 470 mA for Model K110, and dynamic currents with large step discontinuities will cause the red LED to turn ON. -

Page 19: Oscilloscope Measurement Example (K110)
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. - Page 20 DC Zero 16.7mA Figure 14 Model K110 Resolution: 1mV Resolution: 10mV Resolution: 100µV Display Error: 0% Display Error: 0% Display Error: 1.8% PUSH PUSH PUSH DC Zero DC Zero DC Zero 16.7mA Figure 15 DC/AC MicroProbe Models K100 and K110...
- Page 21 • Do not allow probe jaws to abruptly snap closed from the open state. This can lead to residual readings. If this happens, the Model K100/ K110 will need to be rezeroed. • Beware of short-circuit currents. Large in-rush currents (which can occur when power is first applied in a circuit) and large high-current transients may cause varying degrees of residual readings.
-
Page 22: Residual Readings Following Severe Overloads
4.6 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. -
Page 23: Maintenance
OFF and disconnect the unit from all circuits before opening the case. 5.1 BATTERY INSTALLATION Your Model K100/K110 has been shipped with a new 9 V battery installed. To replace the battery: • Remove probe from any conductor and place it away from any active conductors, circuitry, etc. -
Page 24: Cleaning
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). Figure 17 DC/AC MicroProbe Models K100 and K110... -
