Tính năng Thiết bị đo đa năng Fluke 1654B:
Safer, easier installation testing.
The 1654B Installation
Tester verifies the safety of electrical installations in domestic, commercial
and industrial applications. It can ensure that fixed wiring is safe and
correctly installed to meet the requirements of IEC 60364, HD 384 and all
relevant local standards
Faster
- Two
measurements at once and a dual display. PEFC/PSC and loop impedance are
measured and displayed in parallel, saves you more than 50% of test time
compared to other loop testers.
- Additional
new high current loop mode. Faster measurements compared to loop tests
with non-trip mode for RCD’s.
- Unique
zero adapter for fast, always reliable and accurate test lead and mains
cord compensation.
- Fast
voltage measurement between L-N, L-PE and N-PE using the mains cord. No
need to change measurement connections.
|
Safer
- Earth
Volt Touchpad detects raised earth voltages >50 V, indicating
potential dangerous situations.
- Supplied
with the SureGrip™ test leads and clips which gives the user a
comfortable, reliable grip
|
Easy
- Rotary
dial knob indicates clearly which function is selected, all
functionalities on one spot and no complex multi level menus.
- Large
display with backlight, clear symbols with exceptionally wide viewing
angle for easy and safe readings.
- PASS/FAIL
indication for RCD test results.
- Variable
RCD current mode for customized settings.
- Loop
& Line Resistance - mΩ resolution
- Test
smooth dc sensitive RCDs (Type B)
- Extended
Memory
- Extended
documentation mode (UK only)
|
Rugged & lightweight
Withstands a drop of 1 meter.
Compact, lightweight (less than 1.3 kg)
and padded neck-strap to free your hands for all day testing.
Complete kit
All 1650 models are equipped with detachable
leads that can be replaced in case of damage or loss. A durable hard case will
protect your instrument in tough field conditions.
Slim probe design with test button
Keeps your eyes on the panel while probing hard
to reach points. This remote probe is powered by the tester so always operable
(does not require additional batteries).
Zero Adapter
For easy, always reliable and accurate
compensation of test leads and mains cords. This adapter can be used for all
different kind of mains plugs as well as test accessories like probes,
alligator clips etc.
