Taking accurate current measurement can be difficult when dealing with the wrong tools or a challenging workspace. Placing your trust in a machine requires it to deliver reliable results, regardless of the conditions.

To solve both of these problems, Testo has released the testo 770 clamp meter range. The revolutionary design overcomes the issue seen by so many other clamp meters; standard clamping makes it incredibly difficult to move when cables are in close proximity to each other.

With the testo 770 range, the clamp mechanism features a sliding leg - allowing users to avoid touching cables - and uses the hook-clamp design to provide factual, safe results.

Precise and automatic readings

The testo 770 range features an auto-mode where the user is able to select the automatic recognition and adjustment of AC/DC voltage and current. This provides the automatic recognition of resistance, diode or capacitance, while a manual select button allows the user to force the device into a specific manual mode when needed.

The testo 770 also provides clear results, with the display of the 770 range nearly 50 per cent larger than other competitive brands.

“Accurate current measurement is at the heart of the testo 770 family”.

Accurate current measurement is at the heart of the testo 770 family. While averaging meters will only record the ideal voltage that often never appears in actuality, a true root mean square (TRMS) reading includes the real-world voltage, providing an increase of accuracy over an averaging meter by up to 40 per cent.

The testo 770 family functionality

The testo 770 range proves to be incredibly viable for contractors, with the entire 770 family promoting exciting features. All testo 770 clamp meters are equipped with Inrush current measurement - the higher-than-normal current experienced when motors are started.

In every gas-based heating system, there are flame rods that control the burner ignition. The testo 770-2 and 770-3 provide accurate reading of these rods' parameters - a crucial process for the business of heating contractors.

Not only that, the 770-3 also provides Bluetooth functionality, offering the ability to share clamp meter values across other devices such as thermal imagers. This also allows users to analyse values on the Testo Smart Probes App and send reports.
