Unique design for safety and comfort
Rotary mechanism for clamp jaws:
In conventional clamp meters display, keys and clamp jaws are in the same plane.
When current measurement is to be done on vertical bus bars, over head cables,
cables in congested places user connect the clamp meter but the keys and display
may not be visible, hence not able to take the readings or operate the keys.
To over come the above mentioned problem Clamp meter 400A/1000A has a
unique feature called“Rotary mechanism for clamp jaws”. In this, the clamp jaws
are rotating. Hence it is possible to align the clamp jaws as the orientation of
bus bar/conductor while keeping Display and keys facing the user, so that user can
take the readings and operate the keys.
Rotary clamp jaws can be rotated at different angles with the step of 30º, maximum
up to 90º in both clock-wise as well as anti-clock wise direction as shown in figure 9.2
Note :- For better accuracy of current, position conductor at the marking on
the jaw (center of the jaw)

POWER Display Ranging For 1P2W, 3P3W and 3P4W
For measurement of power total 4 Ranges are available 9.999 kVA,
99.99 kVA, 999.9kVA and 9999 kVA same applicable for hp, kVAr and kW.
Meter will select range of all powers i.e. kW, hp and kVAr based on
kVA reading.
For example :V = 230V, I = 102A and Angle = 0 then kVA = 230*102 = 23.46 kVA
kW = 230*102 * COS 0 = 23.46 kW and kVAr = 230*102*SIN 0 = 0 kVAr
So Meter will display power like 23.46 kW, 00.00 kVAr, 23.46 kVA
With same V & I now if Angle = 70 then,
kW = 230*102 * COS70 = 8.023kW and kVAr = 230*102*SIN70=22.04 kVAr
Now Meter will display kW like 8.02 and not 8.023 as kVA is in 99.99 range.
hp Range is also based on kVA range except some cases where it is
displayed one range higher than kVA.
For example :kVA = 82.53 so at maximum value of kW = kVA at PF = 1,
hp = kW / 0.7456 = 110.0 so in this case hp is display in 999.9 range.
9.999 kVA range is only applicable for V <100 V and I < 100 A.
If V > 500 V and I < 25 A then, In this kind of situation a very small amount
of current can cause a large amount of fluctuation in power reading.
To avoid this irritation of fast display fluctuation because of small current
change meter will display power in 999.9 kVA range.
All this ranging related logic is equally applicable for DC power ( In DC
POWER ranging is based on kW as there is no kVA), 3P4W balance as
well as un balance and 3P3W balance as well as un balance system type.
