3 Preparation
When you start using the instrument for the first time after factory shipment or resetting it to
factory settings, be sure to complete the following preparation procedures.
z Wiring checking
z Initial set up
z Calibration
 Wiring checking
Check the following.
z Are the power cable, sensor cable, and transmission cable properly wired?
z Are the terminal block screws firmly tightened?
z Is the fluctuation of the power supply voltage within ±10% of the rated voltage?
 Initial set up
When the instrument is powered on in the factory setting state, it starts up in the Maintenance
mode.
Check the current settings referring to Table 1.
If necessary, change settings following the instructions in “4.2 Basic settings” (page 19).
To finish the initial setup, press the MEAS key repeatedly until the MEAS lamp lights up to go
to the measurement mode.
Once the initial setup is finished, the instrument starts up in the measurement mode since
then. This is the normal measurement mode.
