A wide variety of industrial and commercial applications, including scheduled maintenance, warranty
and leasing – for medical equipment, transport and industrial vehicles and other industrial equipment.
FEATURES
▶
▶
All-8’s LCD function test: each digit displays an eight for
one second after power-up.
Attractive 6-digit LCD 5mm or 7mm high digits
(7mm with optional backlighting) are much easier
to read than electromechanical meters, which
have only 3mm high digits.
Silent operation – no moving parts. Eliminates
annoying gear and motor noise.
Exceptional reliability due to nonvolatile memory
(EEPROM) which retains data for 25+ years.
Wide voltage ranges, for example, one unit
can be powered from 75 to 270 VAC anywhere
between 48 and 440 Hz – ideal for distribution
and worldwide markets without having to
stock multiple model types.
Electrical reset (optional).
Available in ten case styles – all fit in standard
hour meter/counter cutouts.
Multiple mountings available – Metal U-bracket, “U” clamp/
stud (D, Q, R and S cases), flange mount with hardware
(F, T, G, J cases), or mounting clip (G, L, Y, Z, cases).
Backlit units allow external illumination control,
i.e., on/off or dimmer (12VDC only).
Flashing hourglass icon indicates when the hour
meter is accumulating time.
Memory will arm only when power has been applied
for five seconds (with no loss of time or counts).
Low power consumption.
UL and CE recognized.
