FEATURES:
THIS PRODUCT IS SOLD OUT/HAS BEEN DISCONTINUED
The display unit demonstrates IP53 protection level and is resistant to dripping water and dust.
The built-in battery, if fully charged, allows approximately 500 measurements to be made.
A convenient carrying case is supplied as standard for protecting the instrument in the field.
Up to 10 measurement results can be saved in the built-in memory.
Measurement results appear in large characters on the large LCD screen. Results can be confirmed at a glance.
Detailed set-ups, such as change of standards and cutoff lengths, can be made by pressing the relevant buttons after sliding back the top cover.
The SPC connector for Digimatic output and the RS-232C output connector are provided on the rear panel of the display unit for data output to external devices.
Printout of recorded profiles is also possible if the tester is connected to the dedicated hand-held, built-in battery operated compact SJ-printer (optional).
