FEATURES AND BENEFITS
Electronically Controlled Resistance Box
Your
ohm Source Se ries
The ohmSOURCE Resistance Box product line is
like nothing you have ever seen be fore! Mi cro pro -
ces sor-controlled and loaded with innovative fea-
tures, the ohmSOURCE Re sis tance Box succeeds
in providing highly accurate and precise resistance
values in an intuitive and user-friendly fashion.
With a resistance value range of up to 24 MΩ
and a power rating of up to 1 Watt, the handheld
ohmSOURCE is practical for all industries including
au to mo tive, medical, test & mea sure ment, tele com -
mu ni ca tions, and HVAC.
Automatic RTD simulation
The Translation Table Add-on enables the user
to download and store data tables in the ohm-
SOURCE Resistance Decade Box for translating
a known, user-defi nable physical characteristic
into a resistance value. Use this option to simulate

Enter resistance values using a calculator-style keypad.
Recall up to four frequently used resistance values with one
touch.
Store resistance values in up to 10 additional mem o ry locations
(0-9).
Limits the amount of current passing through the ohmSOURCE
to prevent possible damage.
Change resistance by user-defi ned increments or select stan-
dard resistance values (1%, 5%, 10%)
Conveniently 100% mechanically isolate the ohmSOURCE from
the application with the touch of a key.
The output resistance value, in ohms, is easily read from the
large, graphical LCD display.

Tradition
any type of transducer that
converts a physical phe-
nomenon into a re sis tance
value: ther mistors, conduc-
tivity sensors, etc... Each
table may contain up to 256
equivalences.
Using the RS-232 interface
and the Software De vel -
op ment Kit, you can control
the ohmSOURCE from a
remote computer and design
automated test equipment to
fi t your custom application.
Uses real resistors.
Automatic Residual Resistance
Auto-Off Power
Field Calibration
FLASH Software Updates
Accessories
The residual resistance of the ohmSOURCE is auto mat i cal ly
included in the output re sis tance value.
No zero sub trac tion is required.
The ohmSOURCE automatically shuts off after 4 minutes of
inactivity to conserve power.
Easily calibrate the ohmSOURCE with a high precision ohm-
meter. Annual factory calibration recommended.
The microprocessor has FLASH program memory to allow
reprogramming of product fi rmware.
