ADInstruments Telegraph for Windows

Display-scaling utility for electrophysiology recordings

ADInstruments Telegraph is a free Windows application that keeps electrophysiology amplifier outputs displayed at the correct scale. It reads the amplifier’s gain-telegraph signal and adjusts the plotting scale automatically so traces remain properly scaled after any gain changes. This removes the need to constantly tweak display settings during experiments and helps preserve visual accuracy in time-sensitive recordings.

How the tool works

The program monitors the amplifier’s gain-telegraph output and uses that information to rescale incoming data in real time. When the amplifier gain is changed, the utility updates the display scaling so recorded signals retain a consistent, meaningful amplitude on-screen. This automated behavior is especially useful in setups where multiple gain adjustments occur during a session.

Who should consider using it

• Researchers and technicians running electrophysiology experiments that require live monitoring of signals.
• Labs in neuroscience, physiology, and related fields where accurate, real-time visualization of amplitude is critical.
• Anyone who wants to reduce display-related errors and focus on data interpretation rather than manual reconfiguration.

Key advantages

• Automatic rescaling keeps traces at the correct amplitude without manual intervention.
• Minimizes mistakes caused by inconsistent display scaling during experiments.
• Frees operators to concentrate on data quality and analysis instead of display settings.
• Works on Windows and integrates with amplifiers that provide a gain-telegraph output.

Suggested alternatives

• SHAREit (free) — a commonly recommended, no-cost option for general file-sharing or quick data transfers between devices.
• Commercial or open-source acquisition packages — many data-acquisition suites include built-in scaling and device integration if you need a more feature-rich environment.

Practical considerations for deployment

• Confirm your amplifier provides a compatible gain-telegraph output before relying on automated scaling.
• Test the utility in a non-critical session to verify scaling behavior with your specific hardware and acquisition software.
• Use it in conjunction with standard calibration checks so that automatic display adjustments match expected signal amplitudes.
