History of SQ
Q: In 1982, we DAIICHI developed an aggregate type transducer ahead of the world. By that time, alphabet that imitates ameasurement element to a model name as a sign conventionally and make it easy to know what the transducer measures.
This all-in-one type transducer assumed the entire normal electricity measurement elements. We take “Q” of “Quality”,
which declared a high quality, and they were born as the QT2 series.
Later, we improved the QT2 series as the current QT2-93A series: more compact, lightweight and multifunction.
In 1997, Multi-meter: QLC-110, in a meaning of Q (high quality) and multi-(many functions) was developed; it has theindication function of both transducer and electric indicator. Afterwards, according to the functions, demand measurement(DLC-110), harmonics measurement (HLC-110), max. & min. measurements (MLC-110) etc. were born, too. They are LC
series.
SQ: In 2006, to summarize these technology and various LC series in 1 (one), we developed the SUPER high quality,
multifunction meter. We named it SQLC-110L. Another reason to use “SQ” is from the name of a hairy giant: an
unconfirmed animal known for BigFoot / Sasquation in Native American words, which means strong.

Support Broadband CT●It combines with broad band CT and support from 40A to 600A.
According to the load increase and decrease etc. the substitution of CT is
unnecessary; it corresponds easily only by changing the CT ratio.
3φ3W (2VT, 2CT) method.
●Measuring display is including one main monitoring, 3 sub-monitoring
and bar-graph display. It supports harmonic monitoring (distortion rate,
RMS value, content rate), too.
●4 analog circuits outputs and 2 contact circuit outputs (pulse, alarm, CPUin abnormal).
