Panel meter users in today’s marketplace should become
familiar with the unique advantages common to digital and
analog meter design when making their selections. Many
already recognize the inherent superiority of the digital meter
under certain applications and the value of the analog
meter in others. While the enormous popularity and
decreasing costs of digital panel meters have made them
the choice of many consumers, there are other factors to
consider when choosing a panel meter.
When precise measurements and resolution are the fore-
most consideration, a Simpson Digital Panel Meter would
be the better choice. Digital panel meters offer accura-
cies ranging from 1% to 0.02%, while the analog counter-
part is typically rated at 2%. Digital displays are easily
read from 20 feet, under poor lighting and with no parallax
problems. (Parallax is an optical illusion caused by view-
ing an object from an angle rather than directly. Since
there is a space between the pointer and the face of the
meter scale, an analog pointer will seem to be at different
positions on its scale, depending on the angle from which
it is read.) Digital panel meters, such as the Simpson
Hawk 3, offer scaling (the capability of the meter to asso-
ciate, in engineering units, any desired value to the elec-
trical input range). This provides flexibility and versatility
for a variety of applications. An additional option is the
RS485 serial interface -- suitable for connection between

a digital controller, personal computer, host computer or
printer -- and unique to digital panel meters. 12DCV and
24DCV excitation outputs are available to power ancillary
devices such as strain gauge bridges and transmitters --
eliminating the need for an external power supply.
Analog and relay outputs are also useful options in many
monitoring and control applications.
Analog panel meters are preferable to digital where read-
ings tend to fluctuate or oscillate and where extended
monitoring is required to indicate trends or rates of
change. Digital sampling times may cause reading errors
and the highs and lows of the swing cannot be identified.
Analog panel meters also provide rugged durability and
dependability to withstand changing outdoor environ-
ments. They are generally easier to read in bright sun-
light or well-lit rooms. And, unlike the digital meter, the
analog meter requires no external power source.
Simpson Analog Panel Meters come in a variety of
designs made possible through customized dials, mount-
ing options (window, surface and bezel) and a large
selection of case styles and sizes.
Simpson panel meter accessories include stock thermo-
couples, current transformers, external portable and
switchboard shunts and external multipliers, transducers,
and transmitters.
