5.2.2 Dial Test
This page can be accessed from
Load Values
screen by
F3
or from
Energy Values
screen by
F2
.
Configuration of Dial tests is in Test Settings menu, where mode (Time or Energy), amount of time /
energy and energy type (Active, Reactive, Apparent) is specified.
When Generator (PTE) has dosage feature enabled (see chapter 4.3.1 Generator Settings) Dial test
automatically controls also start and stop of power generation. When dosage is active (energy is
being accumulated with real-
time generation) red highlighted “Dosage” message flashes on each
screen.
Test is started with
F1
key. After first press initialization occurs and dial test is prepared. At this stage
#1 field
(see picture below) should be filled with initial state of register of electricity meter.
After second press of
F1
key testing begins. If the Generator section is enabled for Dosage,
generation of current and voltage starts automatically.
After third press of
F1
key the testing is aborted by user. If the Generator section is enabled for
Dosage and
“Stop voltage” (and /or current) is also enabled Generator will also cease generating this
quantity (U and /or I). After that user can fill
#2 field
(see picture below). Then Error is calculated.
If the user will not interrupt the testing by third press of
F1 key
PTE will terminate testing automatically
after reaching certain value of energy or time (depends on Test settings).
Note:
Before first initialization (right after Dial test screen is opened) it is recommended to generate voltage
(only) to have such meter under power. This is useful especially for static/electronic meters so user is
capable of performing initial register reading. When Dosage starts (second F1 press) PTE
automatically generates U and I.
COUNTERS Section:
This section is related to the values obtained from meter. Meter connected to the network can
measure quantities via transformer. In such case meter’s parameters can be defined for transformer’s
secondary side (Sec.) or calculated to the primary side (Prim.).
Operator enters initial state of meter counter
#1
before test and final state of meter counter
#2
after
test. Device automatically calculates difference (
ΔE
) and evaluates test error. It is also possible to
define directly the difference (
ΔE).
Energy measurement Section:
This section is related to the energy measurement obtained by device. CT (Current) and VT (Voltage)
ratios are acquired from database. In this window they can be changed (they turn red). By default,
both Prim. / Sec. switches are set to the same value which is associated to database item.
These switches along with CT / VT ratios enable to set where the meter is placed (during
measurement) and where the device measures energy.
Running in Automatic Mode (chapter 4.2.3 on page 27) uses also this mode, which means that during
dial test in Automatic Mode (defined on green screen) actually this Dial test runs in the background on
the blue screen and also all fields are filled. In such scenario fields
#1
and
#
2 are filled automatically
(if optical communication head with static meter is used) or manually
– user must switch into this
screen and fill
#1
at the beginning and
#2
at the end of dial test.
Dial Test runs always simultaneously with Maximum Demand Test which has to last longer than Dial
Test. The reason lies in principle of Dial Test evaluation. This feature offers also evaluation of these
two tests concurrently.
