 If analog readings are used, the response of the recording system should be
checked against a NIST traceable voltage source or meter.
 Data recording devices should be capable of bi-polar operation so that
negative readings can be recorded.
 For electronic data recording, the T802 provides an internal data acquisition
system (DAS), which is described in detail in Section 7 APICOM, a remote
control program, is also provided as a convenient and powerful tool for data
handling, download, storage, quick check and plotting (see Section 8.1.1).

ZERO/SPAN CALIBRATION CHECKS VS. ZERO/SPAN CALIBRATION
Pressing the ENTR button during the following procedure resets the
stored values for OFFSET and SLOPE and alters the instrument’s
Calibration. This should ONLY BE DONE during an actual calibration
of the T802.
NEVER press the ENTR button if you are only checking calibration.
