Compact and handy for absolute and relative measurementThe Voltcraft fiber optic power meter in compact, handy size with its visual fault indication is the perfect partner for absolute and relative power measurements of a total of eight adjustable, calibrated wavelengths. It has a user calibration function, a red laser diode that can be activated and can display linear milliwatt and non-linear decibel milliwatt values simultaneously. The service range is between -70 and +10 dBm. The integrated LCD backlight makes it possible to perform tests even in low light conditions. If the battery is low, this is immediately indicated on one of the two displays. Another practical feature: The impact-resistant measuring device, which is impact-resistant up to a fall from a height of two meters, switches off automatically when it is not used for a longer period of time. And in the carry bag included in the delivery it can be stowed away quickly and easily and transported well protected to the next place of use.This text is machine translated.
