Overview

The Electrocorder EC-2V is a two-channel voltage logger for single-phase voltage investigations where live-to-neutral and earth-to-neutral measurements are both useful.

Use it when a simple single-channel voltage recorder may not show enough context. The EC-2V records live-to-neutral voltage and earth-to-neutral voltage, helping investigate loose neutral, earthing or grounding concerns as well as general high or low voltage complaints.

Best for:

• Single-phase voltage complaints where earth/ground reference matters.
• Investigating possible loose neutral, bad earth or grounding issues.
• Voltage optimisation checks where two voltage channels are useful.
• Facilities and utility support work where socket-level voltage evidence is needed.
• Sites where voltage data is required but current and power are not.

Consider another model if:

• You only need a simpler single-channel voltage logger, where the EC-1V may be enough.
• You need voltage and current together, where an EC-2VA, CT-2VA or EC-7VAR-RS may be more appropriate.
• You need three-phase voltage monitoring, where the EC-3V or SL-3V may be a better choice.

What you get:

• EC-2V logger.
• Voltage lead, USB lead, carry case, batteries, user instructions and free Electrosoft analysis software.
• Two voltage channels for live-to-neutral and earth-to-neutral monitoring.

Set up the logger in Electrosoft, connect it to the socket or voltage point being monitored, then start recording. When enough data has been captured, disconnect the logger, connect it to a PC by USB and use Electrosoft to view, save, export and report on the results.

Applications

Typical applications: The EC-2V is intended for two-channel voltage investigations where a second voltage reference helps explain site behaviour.

What the EC-2V records:

• Live-to-neutral voltage.
• Earth-to-neutral voltage.
• Minimum, maximum and true average values over the selected averaging period.
• Voltage trends that may help identify supply, neutral or earthing-related issues.

Why constant sampling matters: many instruments only take periodic snapshots. The Electrocorder continuously samples throughout the averaging period, helping capture short events, changing loads and trend data that can otherwise be missed.

Recording duration depends on the selected averaging period. Shorter averaging periods give more detail, while longer periods support extended monitoring.

When supplied with the correct plug or voltage lead arrangement, the EC-2V can be used as a practical socket-level voltage logger. It is slightly more capable than the EC-1V because it records a second voltage channel.

Features

When to choose the EC-2V
Choose this model when you need more diagnostic voltage information than a single-channel recorder provides, but still do not need current or power measurement.

Compare with related Electrocorder models
If you only need one voltage channel, consider the EC-1V. If voltage and current together are needed, consider the EC-2VA, CT-2VA or EC-7VAR-RS. For three-phase voltage, consider the EC-3V or SL-3V.

Key features:

• Two-channel voltage logging.
• Measures live-to-neutral and earth-to-neutral voltage.
• Useful for loose neutral, earthing and voltage complaint investigations.
• Configurable averaging period for short or longer-term monitoring.
• Constant sampling to reduce the risk of missing short-duration voltage events.

Measurement note
The EC-2V is a voltage logger. It does not measure current, power or power factor.

FAQ

What is the difference between EC-1V and EC-2V?
The EC-1V records one voltage channel. The EC-2V records live-to-neutral and earth-to-neutral voltage, giving more diagnostic context.

When is earth-to-neutral voltage useful?
It can help when investigating possible neutral or earthing/grounding issues.

Does it measure current?
No. The EC-2V is a voltage logger only.

Can it be used for voltage optimisation checks?
Yes. It can record voltage data before and after optimisation work.

What software is used to analyse the data?
Electrosoft PC software is used to configure the logger, download recorded data, view graphs, export data and create reports.
