Power-on or off the power supply (POWER)
These operations are described in remainder of Section 3.
DISPLAY
The meter has a 5-digit, Liquid Crystal Display (Primary Display) and a 4-digit, Liquid Crystal Display
(Secondary Display). The display shows measurement readings, measurement units and messages.
As shown in Figure 3-1.
INPUT TERMINALS
The input terminals, as shown in Figure 3-2, are located
on the right of the front panel
The meter is protected against overloads up to the
limits shown in Table 3-1. Exceeding these limits poses
a hazard to both the meter and operator.
