Preparing the Instruments
1
Wire the GX/GP and the calibration instruments as shown in the following figure, and
adequately warm up the instruments (the warm-up time of the GX/GP is at least 30
minutes).
2
Check that the operating environment such as ambient temperature and humidity is
within the standard operating conditions (see “General Specifications”).
