Any WaveView windows that are open will change to show streams in
physical units. New WaveView windows will also use these units
where possible.
Each digitiser System ID and serial number can have only one
instrument connected to it. If you have a 6-channel digitiser with two
connected sensors, you will need to make the digitiser announce
different serial numbers for each one. On newer Güralp Systems
DM24 digitisers, this can be done with the command SERIAL2. See
the manual for your digitiser for more information.

The calibration information for a CMG-3T weak-motion velocity
sensor might look like the following:
Serial-Nos=T3X99
VPC=3.153,3.147,3.159
G=1010,1007,1002
COILCONST=0.02575,0.01778,0.01774
CALVPC=3.161
CALRES=51000
TYPE=CMG-3T
RESPONSE=CMG-3_30S_50HZ V
GRAVITY=9.80122
CMG-5TD accelerometers use 1 Ω calibration resistors, and their coil
constant is set to unity. Older CMG-5TD instruments, based on Mk2
digitiser hardware, do not have calibration input facilities, and thus
the CALVPC entry is omitted. For example:
