FEATURES

Safe inspection of solar installations with high voltage

DC High V Probe Mode
- Enables high voltage measurement up to CAT III 2000 V
- Safely measure solar installations like the mega-solar without interrupting the grid by simply connecting the DC High Voltage Probe P2000 to compatible Hioki clamp meters and digital multimeters (DMMs)

See details about DC High Voltage Probe P2000



Helping personnel analyze issues in the field

Harmonic measurement
When combined with GENNECT Cross (*1), you can perform simple harmonic analysis. Applications include harmonic measurement of power conditioners for solar systems and problem analysis of power supply systems.

See here for details about GENNECT Cross

Problems that can be caused by harmonics

• Equipment burn-out and destruction due to overheating
• Malfunctions of power control devices
• Increased loss along with reduced service life and efficiency for power devices

*1:GENNECT Cross is an free app that lets you connect field measuring instruments to smartphones and tablets using Bluetooth® communications. Wireless Adapter Z3210 (sold separately) is required in order to pair the DT4261 with GENNECT Cross.

Wireless communication capability for even greater convenience

Wireless support
When the Wireless Adapter Z3210 is installed, Bluetooth® wireless communication is enabled. It transfers measurements to your smartphone or tablet and allows you to quickly create reports with field photos and drawings.

Excel® Direct Input Function (*2)
Boost work efficiency in the field by letting you directly transfer measurement data to (i.e., enter measured values directly into) templates created as Excel®.

*2:The optional Wireless Adapter Z3210 is required.

Prevents incorrect current measurement

Fuse check function
When switching from the clamp function to the current function, a fuse disconnection check is automatically performed.
This allows the user to know if the fuse is broken before current measurement, which prevents erroneous measurement.



Ensuring safety by preventing erroneous test lead insertion

Terminal shutters
Due to the current terminal’s low impedance, measuring voltage after erroneously inserting a test lead into the current terminal will cause the fuse to blow. The DT4261’s terminal shutters are linked to the instrument’s rotary switch such that they block access to test lead terminals that aren’t being used, making it physically impossible to insert a lead into the wrong terminal.



More recommended features

Stop worrying about losing test lead caps
Test Lead L9300 incorporate integrated caps for greater convenience and safety. The design lets you change the measurement category simply by sliding the test lead’s protective finger guard. You no longer have to worry about losing caps!
