The new OMEGASAYS® digital
multimeter/ thermometer/IR Pyrometer is
a full function digital multimeter which
also features non-contact infrared
temperature measurement, dual
type K thermocouple inputs and voice
annunciation of measured values. This
compact, portable meter measures true
RMS ac voltage and current, as well
as resistance and temperature, and will
accept any two type K thermocouples
terminated with miniature SMP
connectors. The HHM1-IR features a
standard voice annunciation used to
verbally tell the user the current
measurement in a choice of five
different languages.
The OMEGASAYS® displays measured
values on an easy to read LCD for visual
indication, which also includes an
indication of the current measurement
function, the other available
measurement functions, speech function
status (continuous, on demand or off),
measurement units, thermocouple probe
input (T1, T2 or T1-T2), display hold and
low battery. All DMM connections plug
into the front of the unit. Thermocouples,
pyrometer module, earphones and the ac
adaptor plug into the rear panel of the
unit, which also contains a three-position
volume selector switch. On top of the
HHM1-IR meter is an on/off switch along
with six pushbuttons to select from
among a variety of unique additional
functions. These include a “TEMP”
function, which selects IR/thermocouple
input T1, T2 or the differential. The “.
ZERO” function compensates for the
resistance of the test leads when taking
resistance measurements. “DISPLAY
HOLD/SPEAK” selects continuous or
on-demand speech or freezes the
display. The “SPEECH” button turns the
speech function on and off. “°F/°C”
switches the temperature units. “AC/DC”
similarly switches between ac and dc
measurements.
Included with each HHM1-IR is a set of
test leads for measuring voltage, current
and resistance. The red lead handle
includes a convenient pushbutton to
easily operate the speech function while
holding the leads. An optional pistol grip
type K thermocouple handle is also
available with a similar pushbutton to
activate the voice function remotely for
temperature measurements.
