7.3.5 TECH, NIST buffer Calibration
The procedure below is two points calibration of TECH buffer. (The procedure is same as
NIST buffer mode.) First, enter the setup of Multi-points calibration and set the number of
calibration point for 2. (See chapter 6.5 Multi-Cal) Then, go to Calibration menu and select
TECH mode. Operate the instrument as following procedure diagram. For three points calibration,
it also needs to set 3 points in the Multi-Cal setting in advance, and the calibration procedure is
the same.
