THE BECKMAN HD-100
The HD-100, the Hardhat meter, is an indispensible
tool that has rugged protection from mishaps and
adverse environments.
2000-Hour Continuous Battery Life
The common 9V transistor battery provides up to
2000 hours of continuous operation, and up to 2
years of life under typical use. For added con-
venience, the decimal point blinks during the last
ten percent of battery life.
Easy-to-Use Single Selector Switch
Makes the instrument easier to use and saves
time. You get a unique switch design that is far
more reliable and durable than found in conven-
tional VOMs.
lnsta-Ohms® Continuity Indicator
You can make continuity checks with the speed
and ease of an analog meter. The lnsta-Ohms®
Continuity I ndicatorfeatures an ohms symbol that
appears in the display the instant continuity is
established with test leads.
Reliable 100% Factory Burn-In and
Computer Tested
Every function and range is computer tested at the
factory to assure you of a meter that works the
first time, every time.
Maximum Protection RF Shielding
You can enter high RF energy fields generated by
communication transmitters and high voltage
sources with confidence in your results.

caused by circuit loading. Increased measurement
accuracy over other comparable meters is achieved
by providing a high input impedance in all DC
voltage ranges.

Guaranteed Long-Term Accuracy
A highly stable band-gap reference element and
thin-film voltage divider network guarantee the
specified accuracy for a one-year minimum,
without calibration
Fast and Accurate In-Circuit Diode
Transistor Test Function
This special test function allows accurate
measurements of forward voltage drops across
diode, LEDs, and transistor junctions with 2mA of
"constant'' test current Semiconductor junctions
can also be measured while in-circuit with as little
as 500 ohms shunt resistance.
