.3 Power On/Off
(1) Check before power-on
・Unit is correctly installed (
Section 2.1).
・Power cord is correctly connected and unit is properly grounded (
Section
2.2).
(2) Power switch on/off
・There is no need for the user to manually select AC or DC power.
・When both AC and DC power are connected, AC power has priority.
・When AC power is disconnected (or falls under 90 V), the 8835-01
automatically switches to DC. (If the switch of the 9439 is set to ON, the
8835-01 automatically switches to DC even if AC power is disconnected.)
(3) To assure high measurement precision
Turn the unit on and let it warm up for about 30 minutes, to allow internal
temperature to fully stabilize. Then carry out zero adjustment (see Section
7.3.7) and start the measurement.
(4) Power-off
When the unit is turned off, it memorizes the currently used settings and
reestablishes the same settings the next time the unit is turned on again.
