Electronically Controlled Resistance
Box - Your SOURCE of Resistance!
The ohmSOURCE Resistance Box product line is like nothing you
have ever seen before! Microprocessor-controlled and loaded with
innovative features, the ohmSOURCE Resistance 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 auto motive,
medical, test & measurement, telecommunications, 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-definable physical characteristic into
a resistance value. Use this option to simulate any type of transducer
that converts a physical phenomenon into a resistance value: thermistors,
conductivity sensors, etc... Each table may contain up to 256
equivalences.
Using the RS-232 interface and the Software Devel opment Kit,
you can control the ohmSOURCE from a remote computer and design
automated test equipment to fit your custom application.
Uses real resistors!
Keypad Interface - Enter resistance values using
a calculator-style keypad.
Quick Value Keys - Recall up to four frequently
used resistance values with one touch.
Memory Keys - Store resistance values in up to
10 additional memory locations (0-9).
Current Limiter (user-defined) - Limits the amount
of current passing through the ohmSOURCE to prevent possible damage.
Increment Value Setting - Change resistance by
user-defi ned increments or select standard resistance values
(1%, 5%, 10%)
Open Key - Conveniently 100% mechanically isolate
the ohmSOURCE from the application with the touch of a key.
Easy-to-Read Display - The output resistance
value, in ohms, is easily read from the large, graphical LCD display.
Automatic Residual Resistance - The residual
resistance of the ohmSOURCE is automatically included in the output
resistance value. No zero subtraction is required.
Auto-Off Power - The ohmSOURCE automatically
shuts off after 4 minutes of inactivity to conserve power.
Field Calibration - Easily calibrate the ohmSOURCE
with a high precision ohmmeter. Annual factory calibration recommended.
FLASH Software Updates - The microprocessor has
FLASH program memory to allow
reprogramming of product firmware.
