NOTE: The values for phase power factor may be
used to verify correct CT position & orientation.
INSTRUMENT SET-UP
The display shows the CT set-up screen. The instrument
settings are entered from this point, starting with the CT
values.
CT SET-UP
To enter programming mode press
and
simultaneously for 5 seconds. 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 S or T 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 W and S
buttons simultaneously for 2 seconds to enter ‘Fine Adjust
Mode’. This is indicated by a decimal point displayed
immediately to the right of the defined parameter viz: “Ct.” this
enables the CT primary value to be changed in 10A steps until
the desired ratio is displayed. Press the W 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.
PULSE SET-UP
The pulse rate value (PLr) may be set between 0.1 and 100
pulses per unit. Press the S or T 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 W 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 (Pto) allows the meter pulse output and
connected data collection hardware to be tested, regardless of
whether an actual load is present. Press the S button to start
the test. The display will show “Ptr” and both outputs will pulse
simultaneously. This is verified by the front panel l.e.d.s.
Press the S and T together to stop the test and reset the test
counter.
HOURS RUN SET-UP
The hours run preset level may be set between 1% and 100%
of the full scale current. Press the S or T key until the
desired value is displayed. Press the W key to store the value
and advance the page.
