TQ8215 Compatibility
By using "TQ8215 compatible mode", this instrument and the existing model TQ8215 are compatible in
the GPIB remote level.
CAUTION:
1.
The TQ8215 compatible mode is a function to use user programs, which are used in the TQ8215, in this
instrument with minimum modification. However, not complete compatibility is guaranteed because of the
differences such as the function and command processing time between both instruments.
Using the normal mode is recommended because of the function restriction such as status.
2.
The calibration can be performed in the TQ8215 compatible mode, but the calibration method is not compat-
ible.
