4. Operating Instructions

The Fluke 123/003S combines the functionality of an oscilloscope and a multimeter. Familiarize yourself with the front panel controls and display before operation.

4.1 Oscilloscope Function

The two-channel digital oscilloscope allows for viewing electrical signals. It features a real-time sample rate of 25MS/s and a record length of 512 points per channel. Key features include:

• Automatic and Cursor Measurements: For in-depth waveform analysis.
• Edge and Video Triggers: To isolate specific signals.
• Advanced Automatic Triggering: Recognizes signal patterns and optimizes triggering, timebase, and amplitude settings automatically.
• External Triggering: An optical port supports attachment of a Fluke ITP120 probe (sold separately).

4.2 Multimeter Function

The true RMS, 5,000-count multimeter provides accurate readings for both linear and non-linear loads. It can measure:

• AC and DC voltage up to 1,250V
• Resistance up to 50MΩ
• Capacitance up to 500µF
• Frequency up to 50MHz
• Duty cycle from 2% to 98%

Additional multimeter features include:

• Ranging Modes: Manual (user selects range) and Auto (device selects range).
• Relative Function: Sets a reference value and displays subsequent measurements as deviations.
• Touch-Hold Mode: Captures a stable reading.
• Data-Hold Function: Freezes a reading on the display.
• Continuity Buzzer: Confirms electrical conduction.
• Diode Check: Detects proper diode function.

4.3 Display and Data Management

The device features a 2.83-inch monochrome LCD with a resolution of 240 x 240 pixels, equipped with a backlight for visibility in low-light conditions. Up to 10 setups and screenshots can be stored in the internal memory.

The TrendPlot chart recorder graphs minimum and maximum values over time for both oscilloscope and multimeter functions. It can be programmed for various time scales, from 15 seconds per division over 120 seconds to 2 days per division over 16 days.

4.4 Connectivity

An optically isolated RS-232 interface allows connection to a compatible printer for direct data printing or to a PC for data storage and analysis. The SCC120 kit includes an RS-232/USB adapter cable and FlukeView CD-ROM software, compatible with Microsoft Windows 2000 and later operating systems, for enhanced data management.

5. Maintenance

To ensure the longevity and accuracy of your Fluke 123/003S ScopeMeter, follow these maintenance guidelines:

• Battery Charging: Recharge the NiMH battery pack regularly using the provided AC adapter/charger. Avoid deep discharge cycles to prolong battery life.
• Cleaning: Clean the instrument's exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the device and its accessories in the hard carrying case (if included with SCC120 kit) in a dry, dust-free environment when not in use.
• Calibration: Periodic calibration by authorized service centers is recommended to maintain measurement accuracy. Refer to the full user manual for recommended calibration intervals.

6. Troubleshooting

If you encounter issues with your Fluke 123/003S, consider the following basic troubleshooting steps:

• Device Not Powering On: Check if the battery is charged. Connect the AC adapter/charger and attempt to power on.
• Incorrect Readings: Ensure test leads are properly connected and not damaged. Verify the correct measurement function is selected.
• Display Issues: Check for physical damage. If the display is dim, ensure the backlight is enabled and the battery is sufficiently charged.
• Connectivity Problems: For PC connection, ensure the RS-232/USB adapter is correctly installed and the FlukeView software is properly configured.

For more complex issues, refer to the comprehensive troubleshooting section in the full user manual or contact Fluke customer support.
