Operation of Fluke 199C Oscilloscope:

Automatic Operation: This is the simplest and quickest way to capture a

signal, knowing little about what you are measuring.

A. Turn scope on – circular button in lower left hand corner.

B. Push the yellow button labeled “Scope”.

C. Press the lime green Auto/Manual button.

D. Connect to where you wish to measure.

1. The oscilloscope will auto-range to the correct voltage range, time

scale, etc. The trigger will go to “Auto Level”, and the trigger mode

will go to “Automatic”.

2. Adjustments may be made from that point, such as changing the time

scale, voltage scale, readings, using cursors and using screen capture.

Use of “Screen Replay”

A. The scope meter will (automatically) capture up to 100 of the most recent

scope screens. (This is the case whether triggering for the scope is set to

automatic trigger, one shot, or “on trigger”. Each refresh will result in a

screen stored in the memory.)

B. To look at what has been saved, press the “Replay” button.

1. A control panel will appear at the bottom of the screen, allowing you

to scroll through each screen one at a time for a close look, scroll back

one at a time, or hit play and rapidly go through all of the replay

screens.

2. On any recalled screens you may use the cursors and zoom functions

to get a better look at the waveform.

3. Individual Screens may be saved to one of the 15 memory positions.

C. If any scope adjustments are made (time scale, voltage scale, trigger

level, etc), everything previously captured by the replay memory will be

lost.

Use of the Scope Memory

A. Press the light blue “hold/run” button to freeze the scope screen. The

word “Hold” will appear in a box in the upper right hand side of the

scope screen.

Do you have a question about the Fluke 199C and is the answer not in the manual?

This document outlines the operation, screen replay, memory usage, and data transfer capabilities of the Fluke 199C Oscilloscope, along with detailed instructions for capturing fencer and trainer transients.

Function Description

The Fluke 199C Oscilloscope is a versatile instrument designed for capturing and analyzing electrical signals. It offers both automatic and manual operation modes, making it suitable for users with varying levels of expertise. The device can automatically range voltage and time scales, set trigger levels, and store screen captures. It also features a "Screen Replay" function to review past captures and a "Scope Memory" for saving specific screens or setups. The oscilloscope can be connected to a computer for downloading saved screens and waveforms, facilitating report generation and further analysis.

Important Technical Specifications

While specific numerical specifications like bandwidth, sampling rate, or input impedance are not explicitly detailed in this document, several operational parameters are mentioned:

Time Scale: The oscilloscope can adjust its time scale down to 5 nanoseconds per division (ns/division), allowing for detailed analysis of fast transients.
Voltage Scale: The voltage scale can be adjusted from 1 Volt per division upwards, with the ability to change input scales to accommodate signals appearing off-screen or to get a better look at waveforms.
Trigger Modes: Supports "Auto Level" and "Automatic" trigger modes for general use, and "single shot" capture for transients. It also includes "Glitch detect ON" for capturing short-duration events.
Memory:
- Screen Replay: Automatically captures up to 100 of the most recent scope screens.
- Scope Memory: Allows saving individual screens or setups into 15 designated memory positions.
Connectivity: Features an optical coupler for connecting to a computer, enabling data transfer and software integration with FlukeView.

Usage Features

Automatic Operation: This is the simplest method for capturing signals, ideal when the user has limited knowledge of the signal characteristics.

Turn on the scope using the circular button.
Press the yellow "Scope" button.
Press the lime green "Auto/Manual" button.
Connect probes to the measurement point.
- The oscilloscope will automatically set voltage range, time scale, and trigger settings ("Auto Level," "Automatic" mode).
- Users can then manually adjust time scale, voltage scale, readings, and use cursors or screen capture as needed.

Screen Replay: This feature allows review of recently captured screens.

The scope automatically stores up to 100 recent screens, regardless of trigger settings.
Press the "Replay" button to access saved screens.
A control panel appears, allowing users to scroll through screens one by one, or play them rapidly.
Cursors and zoom functions can be used on recalled screens for detailed waveform inspection.
Individual screens from replay can be saved to one of the 15 memory positions.
- Note: Any scope adjustments (time scale, voltage scale, trigger level) will clear the replay memory.

Scope Memory (Saving and Recalling Screens/Setups): This allows users to freeze, save, and recall specific screen captures or instrument setups.

Freezing Screen: Press the light blue "hold/run" button. "Hold" will appear on the screen.
Saving a Screen/Setup:
- Press the "Save/Print" button.
- Press F1 for "Save".
- Use arrow buttons to select one of 15 memory positions.
- Press F4 to save.
- The system will prompt if overwriting existing data.
Recalling a Screen/Setup:
- Press the "Save/Print" button.
- Press F2 for "Recall" or F4 for "View".
- Use arrow buttons to select the desired memory position.
- Press F2 ("Recall Setup") to load the saved setup and screen.

Capturing Fencer and Trainer Transients (Detailed Setup): This section provides specific instructions for configuring the oscilloscope for transient capture.

Maintenance Features

The document does not explicitly detail maintenance features such as calibration, cleaning, or battery replacement. However, the ability to save and recall setups can be considered a form of operational maintenance, ensuring consistent measurement configurations. The process of downloading data to a computer for archiving also contributes to data integrity and long-term record-keeping, which can be part of a broader maintenance strategy for measurement data.
