NOTE: The symbol following the Cos value =
capacitive load.
INSTRUMENT SET-UP
To enter programming mode press and simultaneously
for 5 seconds. The display shows the CT settings screen. The
instrument settings are entered from this point, starting with
the CT values.
CT SET-UP
The CT primary value may then be set from the following
nominal values (secondary value must be 5A):
5, 10, 15, 20, 30, 40, 50, 60, 80, 100, 150, 200, 250, 300, 400,
500, 600, 800, 1000, 1200, 1250, 1500, 1600, 2000, 2400, 3000,
2500, 4000, 4500, 5000, 5500, 6000, 6500, 7000, 7500, 8000,
8500, 9000, 9500, 10000, 10500, 11000, 11500, 12000, 12500,
13000, 13500, 14000, 14500, 15000, 15500, 16000, 16500,
17000, 17500, 18000, 18500, 19000, 19500, 2000, 205000,
21000, 21500, 22500, 23000, 23500, 24000, 24500, 25000
Press the or key until the desired current is displayed. If
the desired CT value is not present in the above list, the ratio
may be ‘fine adjusted’ as follows: Press and hold the and
buttons simultaneously for 2 seconds to enter ‘Fine Adjust
Mode’. This is indicated by the ‘L’ symbol at the bottom left of
the display changing to ‘F’ (Fine). Find mode allows the CT
primary value to be changed in steps of 10A until the desired
ratio is displayed. Press the key to store the value and
advance the page.
VT SET-UP
The default voltage setting is 400V and this value should not be
altered unless the meter is an HV type and is connected via voltage
transformer(s). In this instance the nominal line to line voltage of
the meter must match the secondary voltage of the VT(s) and the
voltage is programmed to the primary voltage rating of the VT(s)
MD INTEGRATION PERIOD SET-UP (in Minutes)
This sets the integration period for the sliding window used for MD
calculation.
Press the or key until the desired value is displayed.
Press the key to advance the page.
CURRENT / VOLTAGE AVERAGING PERIOD SET UP
This sets the integration period (in seconds) for the sliding window
used for average current and voltage calculations. Press the or
key until the desired value is displayed.
Press the key to advance the page.
HOURS RUN SET-UP
The hours run preset level may be set to any desired kW value.
Press the or key until the desired value is displayed.
Press the key to advance the page.
PULSE SET-UP
The pulse rate value (PLr) may be set between 0.1 and 100 pulses
per unit. Press the or key until the desired pulse is displayed.
Note that the unit of energy (Wh/kWh/MWh) will automatically
change to reflect the primary values of CT & VT previously set. The
pulse value is set for both outputs during the process. Press the
key to store the value and advance the page.
The pulse duration value (PLt) may be set in increments between
100mS & 20 seconds as required.
The Pulse Output test allows the meter pulse output and connected
data collection hardware to be tested regardless of whether an
actual load is present. Press the button to start the test. The
display will show ‘run’ and the front panel led will flash to verify a
pulse is being generated. The display will verify the number of
pulses generated.
