Testing Methods and Tools
Using a Serial Port to
Enter TEST Mode
The TEST MODE command, available at Access Level 2, initiates energy
tests (Watt-hour, VAR-hour pulse tests) from any rear-panel communications
port.
Entering TEST Mode
NOTE: Exit any front-panel-initiated
TEST mode session prior to
attempting entry for the TEST MODE
command.
Use a terminal emulation program (Terminal mode from ACSELERATOR
QuickSet
®
SEL-5030 software, for example) and any rear-panel
communications port to enter the TEST MODE serial port command
according to the following syntax:
=>>TEST MODE<name>[TLLC]
Note that M or K prefixes in <name> are interchangeable; resulting energy
value names indicate the same meter register. These prefixes do not affect
scaling of TEST mode pulses, which are in units of Wh.
EXAMPLE 12.1
Entering the following:
=>>TEST MODE MW3I TLLC
causes the meter to enter TEST mode and pulse three-phase Watt-
hours IN on the optical port. Transformer/line loss compensation is
enabled.
Upon entering TEST mode, the meter responds as follows:
TEST MODE ACTIVE
PULSING: KWH3I
ENERGY/PULSE: 1.8000
TCCL: Enabled
Issue command TEST MODE OFF to exit test mode.
=>>
EXAMPLE 12.2
Entering the following:
=>>TEST MODE KVRH3O
causes the meter to enter TEST mode and pulse three-phase Var-
hours OUT on the optical port. Transformer/line loss compensation is
disabled.
Upon entering TEST mode, the meter responds as follows:
TEST MODE ACTIVE
PULSING: KVRH3O
ENERGY/PULSE: 1.8000
TCCL: Disabled
Issue command TEST MODE OFF to exit test mode.
=>>
where:
<name> is a required parameter and can be any energy analog
quantity (excluding Vh)
[TLLC] is an optional parameter that, if included, enables
transformer/line loss compensation in TEST mode
