Chapter 2 Using the Medical Functions mAs Measurements Ω 50 BNC CABLE The mAs function allows you to make mAs (milliampere x seconds) cursor measurements on input A or input B. You can do this on live waveforms, frozen waveforms (HOLD), recorded waveforms, and on saved waveforms.

Fluke 190B/C Medical User Manual • Top right reading, mAs (or As, µAs, etc.): Display the S key labels COPE the integrated current over the time between the cursors. Open the Reading 1 menu Select on A, then accept Select mAs, then accept. This opens the Current Probe menu.
Using the Medical Functions mAs Measurements From step 2, you can also proceed as follows to do mAs Press to highlight . Observe measurements on input A: that two vertical cursors are displayed. In Scope mode display the INPUT key labels. Press to highlight mAs.
Fluke 190B/C Medical User Manual Extended Offset To move the trace: Move the trace up or down until The extended offset function enlarges the vertical trace the ground marker ( ) hits the positioning range for input A and input B to 16 divisions top - or bottom grid line.
Using the Medical Functions Extended Offset Oscilloscopes and dynamic range To prevent waveforms from being distorted, in particular signals with large very steep edges, the signal should stay within the dynamic range, just as with any Oscilloscope. The dynamic range limits are the same as the trace offset limits given in the section Specifications below.
Fluke 190B/C Medical User Manual Triggering Specifications The extended offset range allows you to shift the signal up Maximum trace offset with respect to center screen: and down. Be aware that only the “visible” part is sampled Vertical ranges 2 mV to 50 mV/div (direct 1:1): by the ADC, and that the trigger level has to stay in the positive going signals ........
Using the Medical Functions Smart Average Jump to the Average: field. Smart Average Most users do not like to use averaging as the standard Select On… to open the Average default mode. Occasional deviations in a waveform just menu. distort the averaged waveshape, and do not show up on screen clearly.
Fluke 190B/C Medical User Manual Smart average vs. normal average Normal average smoothes the waveform of repetitive signals. It gives you the averaged waveform over successive acquisitions. A single waveform that deviates strongly will affect the smoothed waveform. This happens for example when looking at an interlaced video system.
Using the Medical Functions Non Interlaced Video Triggering Non Interlaced Video Triggering Select Non interlaced to open the Scan rate menu. To select triggering on a non interlaced video signal, do the following: Select the required Scan rate and Apply a video signal to the red input A. confirm the selection.
