SOLID STATE DIGITAL HOURMETERS & COUNTERS
700 SERIES
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).
DESCRIPTION
The Curtis 700 Series are highly reliable solid state hour
meters and counters that offer an unprecedented combination
of patented technology, performance, reliability and value.
MODEL 700: 2-Wire Hour Meter, displays only when powered.
Available in AC/DC.
MODEL 701: 3-Wire Hour Meter, has a provision or continuous
display. Available in AC/DC and DC-only.
• 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).
MODEL 703: Pulse Counter. Available in AC/DC and DC-only.
• Flashing hourglass icon indicates when the hour meter is
accumulating time.
APPLICATIONS
• Memory will arm only when power has been applied for five
seconds (with no loss of time or counts).
A wide variety of industrial and commercial applications,
including scheduled maintenance, warranty and leasing – for
medical equipment, transport and industrial vehicles and other
• Low power consumption.
• UL and CE recognized.
