Introduction
Congratulations on your purchase of the Extech SL130 Sound Level Alert. Designed for
wall mount, desk, tripod mount or hand held operation, this meter meets ANSI and IEC
Type 2 Sound Level Meter standards. Included is a High/Low Limit Set Point with 4 two
color high intensity LED limit exceed indicators and a large OVER indication when the set
level is exceeded. An Alarm Output can be used in conjunction with the optional Alarm
Module Kit to power a larger or a remote indicating device such as a “QUIET” sign.
Professional features include programmable A/C Weighting and Fast/Slow Response time,
Max Memory with time stamp, and a Clock display. The microphone can be rotated 180
degrees to accommodate any meter location or it can be placed at a remote location using
the optional Remote Microphone Cable. A programmable ON/OFF time extends battery life
to 30 days when programmed 8 hours per day. The bright LED’s are functional only when
the AC power adaptor is used. Careful use of this meter will provide years of reliable
service.
