The De Facto Equipment for
Maintenance and Inspection of Electrical Equipment
Thanks to their ability to safely measure current flow
without requiring that power lines be disconnected, clamp on ammeters
have become required equipment for the technicians who are responsible
for maintaining and inspecting electrical equipment in factories, office
buildings, and other facilities. These instruments must deliver
unmatched ease of use in the field in the form of exceptional
operability and portability. The CLAMP ON HiTESTER 3291 and CLAMP ON
LEAK HiTESTER 3293 have been designed to offer just these
characteristics. |

Overview |
|
|
| The convenience of being
able to safely measure currents without the need to disconnect power
lines has made clamp on current meters the required equipment for the
technicians who are responsible for maintaining and inspecting new and
existing electrical equipment at locations such as factories and
offices. Market research indicates that most of the clamp sensor damage
and other problems that these instruments frequently experience is
caused by excessive twisting in confined spaces, particularly when
technicians must forcefully rotate the tool in an effort to see the
display during measurement. The CLAMP ON HiTESTER 3291 and CLAMP ON LEAK
HiTESTER 3293 address these issues with newly developed low-profile
sensors and a movable display, ensuring unmatched ease of use in the
field. The new models meet technicians' demands for easy operability in
on-site measuring applications with exceptional portability and
full-featured measurement functionality. |

Advantages |
|
|
- Compact, low-profile sensors
- The 3291 measures conductors up to 30 mm in diameter with a
low-profile sensor core that's just 8 mm thick. It can be clamped in
place to measure circuit breakers and other conductors as long as
there is at least 12.5 mm of space available between wires. The 3293
measures conductors up to 24 mm in diameter with a low-profile sensor
core that's just 11 mm thick. The core's concentric design acts to
reduce the influence of magnetic fields from nearby power lines, even
when measuring leak currents.
- Flip-down display
- The ability to rotate the display through 180° keeps readings
visible regardless of the configuration of the wiring being measured
and its location above or below the user. The display also reverses
automatically for additional operability.
- True RMS -
The rapid adoption of equipment such as inverters has caused many
circuit current waveforms to be distorted. The 3291 and 3293 use a
True RMS rectification method to ensure accurate current measurement.
- Built-in filter for rejecting the
high-frequency component - The
widespread use of filtered earth leakage circuit breakers (ELCBs) has
increased the need to reject the high-frequency component when
measuring leak currents. A filter approximating the characteristics of
an ELCB enables the 3291 and 3293 to take measurements after rejecting
the high-speed component.
- Safe, CE Marking compliant design
- The 3291 is CAT IV 300 V (CAT II 600 V) compliant, while the 3293 is
CAT III 300 V compliant. Both models can be used with 3-phase 4-wire
440 V lines.
- Wide dynamic range and application-specific
measurement ranges - With 3 measurement
ranges extending from 60 A to 1000 A (AC), the 3291 is designed to
measure load currents in typical circuits. The 3293 features 6
measurement ranges extending from 30 mA to 1000 A (AC) that can be
selected according to the measurement application, enabling it to
measure everything from minute leak currents to load currents in
typical circuits.
- Unmatched ease of use
-
- Start measuring with a single action. Opening the
jaws powers on the instrument and activates the auto range feature
so you can start taking measurements immediately. Auto power off
helps prevent battery wastage.
- A backlight lets you read measurements in dim
locations.
- A peak value display makes it easy to measure
fluctuating load currents and leak current fluctuations.
