- Sound level meter
Large LCD display, easy to read.
Frequency weighting networks are deigned to meet IEC 651 type 2.
A & C weighting networks are conformity to standard.
Time weighting (FAST & SLOW) dynamic characteristic modes.
AC/DC output for system expansion.
Built in calibrator VR on front panel.
MAX HOLD function for storing the maximum value on display.
Warning indicator for over and under load.
Small, light weihght design allows hand operation.
18mm LCD, 3.5 digits
