When measuring AC Voltage > 750 V, DC Voltage > 1000 V,
ACA > 400.0 A / ACA > 1000 A, the buzzer will
keep sounding as the overload warning.
Approximate 1 minute before the meter is auto power off,
the buzzer will raise constantly 5 sounds to warning.
Before the meter is power off, the buzzer will raise one long

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.
For accurate readings keep the conductor at center position of the jaws as shown in figure c

Normally, it is diffcult to access the middle busbar for current measurement.
With ‘Rotary mechanism for clamp jaws’ it is easy to access middle bus bar,
while keeping display and keys facing towards the user as shown in figure e
on previous page.
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 30 maximumº,
up to 90 in both clock-wise as well as anti-clock wise direction as shown in figure d.º

Safe trigger mechanism
The conventional clamp meters have trigger mechanism either near to
left jaw or right jaw. While taking measurements on bare bus bar or bare
conductor the user’s hand comes very close to bare bus bar/conductor,
which increases the risk of electric shocks to the user.
Also in conventional clamp meters trigger is operated with single finger,
usually a thumb which causes fatigue to the user while opening or closing
the clamp jaws.
To over come the above mentioned problems, Clamp meter 400A/1000A
has a unique feature called ‘Safe trigger mechanism’ in which trigger is
located at bottom side of the clamp meter and far away from the jaws
and hence the bus bar.
So user’s hand is at safer distance from bare conductors, hence minimizes
the risk of electric shock to the user. This is shown in figure f.
Also trigger can be comfortably operated with more than one finger which
eliminates fatigue to the user.
