Casella CEL CEL-62X - Manual (Page 25)

TRIPOD MOUNTING
Socket to mount on standard 1/4" (Whitworth) camera tripod thread.
DISPLAY
320x240 Transmissive Colour TFT. Update period 0.5 seconds.
MEMORY
Micro SD 1GB Non-volatile internal.
CONNECTIVITY (Refer to Figure 18)
USB: Mini B to download to dB36 software or to explore via Windows Explorer to
obtain .CSV file.
AC OUTPUT: Via 2.5mm stereo audio jack (Barrel ground, Tip AC output) provided
for remote monitoring, DAT tape / PC wav file recording or headphone applications.
Approx 0.4V RMS full scale output corresponding to 96dB. Output impedance approx
2.2k
Ω. Load impedance should be as high as possible, and for connection cable in
excess of 0.5 metres coaxial cable should be used. It is recommended that cable
length should be kept to below 10 metres.
The AC output corresponds to the Z weighted response of the sound level meter.
DC OUTPUT: Via 2.5mm stereo audio jack (Barrel ground, Ring DC output) provided
for chart recorders, loggers etc. (note: some offset and scaling will be required on the
measuring system for accurate measurements).
Approx 1.4V DC full scale output corresponding to 140dB. Output impedance approx
2.2k
Ω. Load impedance should be as high as possible.
The DC output corresponds to the A weighted, Fast time response of the sound level
meter.
Note: DC power input ground should be kept isolated from any signal ground.
