OHM SOURCE PROCESSOR CONTROLLED RESISTANCE DECADE SIMULATOR

ohmSource Microprocessor Controlled Resistance Decade Box
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 M and a power rating of up to 1 Watt, the handheld ohmSOURCE is practical for all industries including automotive, medical, test and measurement, telecommunications, and HVAC. Using the RS-232 interface and the Software Development Kit, you can control the ohmSOURCE from a remote computer and design automated test equipment to fit your custom application. 

Keypad Interface
Enter resistance values using a calculator-style keypad instead of unreliable switches and dials.
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
Limits the amount of current passing through the ohmSOURCE to prevent possible damage.

Increment Value Setting
Change resistance by user-defined 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.
Auto-Off Power
The ohmSOURCE automatically shuts off after 
4 minutes of inactivity to conserve power.
RS-232 Interface Capability
Use the RS-232 interface of your computer to control your ohmSOURCE remotely or to download sensor translation tables. Software Development Kit required.
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.
