3.1 Power-on
CAUTION
Turn on the power after making sure that MT8820A is dried
up well. When using MT8820A at normal temperatures
after using it at low temperatures near 0°C, drops of water
produced inside may constitute a short circuit thus causing
failure.
To power on MT8820A, turn on both the main power switch on the rear panel and
the power switch on the front panel.
[Procedure]
1. Turn on the main power switch on the rear panel. This turns on the Stby lamp
on the front panel. The illuminating Stby lamp indicates that the main power
switch is on.
When turned into Standby status, preheating of the reference crystal oscillator
circuit starts. To operate MT8820A at lower temperatures, preheat MT8820A
at least 24 hours to enhance stability of the crystal oscillator.

2. Next, hold down the power switch on the front panel for at least one second to
turn it on. The Stby lamp goes Off and the power On lamp goes On.

3. Some time after the power lamp goes on, various messages are displayed on the
screen and the measurement software is started.
Note:
To switch between power On and Off, you must hold down the power switch
on the front panel for at least one second. This is to prevent the power from
being turned On or switched to standby (Stby) by mistake.
