LCD Shock Mounted
The 3½ digit LCD is shock
rrnunted to reduce breakage.
THE .BECKMAN HD-100
The HD-100, the Hardhat meter, is an indispensible
caused by circuit loading. Increased measurement
accuracy over other comparable meters is achieved
by providing a high input impedance in all DC
voltage ranges.
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.
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
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.
Completely Equipped to Handle
Your Toughest Jobs
Each unit comes fully equipped with a 9V battery,
safety-designed test leads and operato(s manual.
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.
High Accuracy 22-Megohm Input
Impedance
This special feature reduces errors commonly
Water-tight
Seal
Heavy duty sealing
locks out dirt grime
and moisture.
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.
lnsta-Ohms® Continuity Indicator
You can make continuity checks with the speed
and ease of an analog meter. The lnsta-Ohms®
Continuity Indicator features an ohms symbol that
appears in the display the instant continuity is
established with test leads.
Maximum Protection RF Shielding
You can enter high RF energy fields generated by
communication transmitters and high voltage
sources with confidence in your results.

THE BECKMAN DM25
DIGITAL FEATURES ... AT AN ANALOG PRICE
The Beckman DM25 digital multimeter gives you a wide range of
features at a down-to-earth price.
Features like . . .
• Five AC and DC voltage and current ranges
• Six resistance ranges
• A diode test function to test junction forward bias
• An instant continuity beeper to make circuit tracing ·easy
• A capacitance test function
• Dual voltages for in-circuit or out-of-circuit resistance tests
• Conductance to measure extremely high resistance values
• Auto-polarity, auto-zero and auto-decimal capabilities to
eliminate guesswork.
• A single function- and range-selector switch for sure and easy
use.
This pocket-size meter is the best low-cost digital multimeter you
can buy. It measures approximately 53/e" in length, 3¼" in width
and less than ¼" high. It weighs only 5. 75 ounces including
battery.
Also included with your DM25 is a test lead set spare fuse(2A),
a 9V battery and instruction manual. Your meter is backed by the
Beckman warranty.
