By stretching the neck the stiffness that can cause aches and pains and lead to further inflammation can be relieved, often resulting in the improvement of the symptoms associated with a pinched nerve.
CDCSS or Digital Code Squelch (DCS) is a further development of the continuous tone-coded squelch system or CTCSS that uses a slow-speed, binary data stream passed as sub-audible data along with the transmission. Motorola calls this Digital Private Line or DPL.
CTs do not measure DC curent or the DC offset component of an AC signal. For most AC power applications this is not necessary. When DC measurement is needed, the NI 9227 has built-in calibrated shunts and can measure DC current up to 5 Amps. To measure more than 5 Amps DC, a high power current measurement shunt (see below) or Hall Effect sensor (see below) connected to the appropriate measurement module is used.
