Current Conversion Ratio
It can be adjusted between 5.00(/5) and 9999(/5). If this
parameter changes, upper limit value is set to maximum scale
,minimum limit value is set to minimum scale and hysteresis
Measuring Method
It can be adjusted to ac , dc or acdc. LEDs on the top of the
display indicates the adjusted measurement method.
Decimal Indicator
If measured value is lower than 10, it can be shown as (0.000),
(0.00), (0.0) or (0), (For DC measurements (0.00) ).
If measured value between 10 and 100, it can be shown as
(0.00) ,(0.0) or (0), (For DC measurements (0.0) or (0) ).
If measured value between 100 and 1000, it can be shown as
(0.0) or (0), (For DC measurements only (0).
If measured value is higher than 1000, it can be shown as (0) (For
DC measurements only (0) ).
If device includes relay, dPnt type may change according to
relay parameters value.
Samping Time
If 1 ( 1 ) is selected ; sampling time of the measurement is 250ms,
If 2 ( 2 ) is selected, it is 500ms.
If 3 ( 3 ) is selected, it is 750ms.
If 4 ( 4 ) is selected, it is 1 second.
Device Address
It can be adjusted between 1 - 247 .
Baud Rate
It can be adjusted as OFF, 1200, 2400, 4800, 9600,
19200, 38400, 57600 and 115200

Can be adjusted as n.o or n.c .
If n.o is selected, in case of alarm, Alr relay is activated.
Alarm Upper Limit Value
It can be adjusted between minimum and maximum scale
that is specified with c.tr.r parameter. This parameter
can’t be lower than H5Et value.
