1.2.2.4
Test Multiple
A numerical value normally associated with timing tests. Multiples are normally expressed in terms of
whole numbers like 2, 3, 4, etc., times the Pickup or Tap value of the device under test. Fractions of test
multiples may also be entered and the appropriate test values and theoretical trip times will be calculated
automatically.
1.2.2.5
Frame Size
The frame rating is the maximum continuous current rating in amperes of all parts except the overcurrent
device. All current-carrying parts, contacts, and pivot points are designed to carry current up to the frame
size rating without exceeding heating limits.
1.2.2.6
Continuous Current Rating
The continuous current rating is a current value equal to or less than the frame rating. This value of
current is printed or stamped on the overcurrent device. It is possible to have a 600-ampere frame rating,
with a continuous current rating of only 100 amperes (due to the size of the overcurrent trip device).
1.2.2.7
Expected Trip Time
A numerical value representing the expected operating time of the device under test.
1.2.2.8
Interrupting Rating
A numerical value associated with the highest current at rated voltage that the device can interrupt
without external damage.
1.3
Power Over Ethernet Input Power
The STVI gets Power Over Ethernet (PoE) of 48 Volts DC at 0.5 A from the SPI STVI port.

SETUP
2.1
Unpack System
Unpack the unit and check for evidence of any shipping damage. If there is any visual damage,
immediately notify the freight carrier to make a damage claim, and notify Megger of the damage.
2.1.1
Initial Start Up
1. With the Ethernet cable supplied with the unit, connect the STVI Ethernet Port on the SPI unit to
the Ethernet port on the top of the Smart Touch View Interface (STVI).
2. Before connecting power to the unit, make sure the SPI POWER ON/OFF Switch is in the OFF
position (0). Plug the unit line cord into an appropriate power source and turn the POWER
ON/OFF Switch to ON (1). As the SPI unit goes through its power up sequence, in about a
minute the STVI power up screen will appear, then the manual start up screen will appear.
2.2
Communication Ports
There are two types of communication ports on the STVI, one Ethernet, and two USB ports. On the SPI
unit there is a USB port and three Ethernet ports.
