Description

Compact ergonomics.

The safety testers of the Handheld class are used to measure PE/ Ground resistances, insulation resistances and to perform a simple functional test.
The small and sturdy universal testers are intended for standard-compliant safety tests in workshops and production as well as for mobile operation during repair, installation, service and more.

The compact tester´s main application field is the operation at the customer´s premises. Due to this, the test equipment is installed in a robust continuous casting housing. Thanks to the integrated storage and a smart interface, the test results do not have to be manually noted but may be transferred to and processed by the PC. 

The PE/ Ground resistance test is performed with 10 A AC and in precise 4-wire-technology.  Either the resistance or the voltage drop may be evaluated. 

The insulation resistance test´s evaluation is regarding resistance or current.

Additionally, Handheld-testers enable the operator to increase the insulation resistance test´s voltage to max. 25000 V DC. From this, an interesting alternative to the high voltage test with AC is given. 1800V ACeff correspond to approx. 2500V DC.

A wide range of accessories, like transport case and carrying strap to hang around the neck, facilitates the operator´s daily work.

There is a multitude of different models and layouts in the Handheld-class available.

 

 

 

 

 

 

Applications

Service. Indoor. Outdoor.

Machinery Directive (EN 60204)

Handheld used to check an installed system´s compliance with the Machine Directive.

---

Inspection of lightning protection on wind turbines

The Handheld´s ease of use has also proven successful during on-site operations.

The lightning conductor´s reliability is checked from the rotor blade tips to the tower´s bottom.

---

Safety inspection for hospitals 

Typical application to inspect the PE-conductor and the insulation of medical products after repair or maintenance.

Options.

 

Carrying strap

If requested, a carrying strap may be attached to the Handheld to allow the operator to hang it around the neck.  Thus he can use both hands to operate the tester. Due to the mirror-inverted configuration of the most important operating buttons on the left and also on the right side, the tester may be easily operated by left- and right-handers.

Transport case

A robust case protects the tester during transport.

Option 1: Tester and assessories are stored in the designated spaces provided inside the transport case.
Option 2: As an alternative, we also deliver transport cases, in which the tester is loosely put inside.
