- The revolutionary ohmSOURCE Microprocessor Controlled Resistance Decade Boxes are like nothing you have ever seen before!
- Two cost-effective models available
- Accuracy's as tight as 0.01%, with resolution as good as 0.01Ω
- Enginnered as an ideal RTD Calibrator
- Unit can only be used as a MANUAL unit. Can not be connected to or controlled by a computer
Microprocessor-controlled and loaded with innovative features, the ohmSOURCEResistance Decade Boxes 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 decade boxes are practical for all industries including automotive, medical, test and measurement and telecommunications.
FEATURES AND BENEFITS
Keypad Interface Enter resistance values using a calculator-style keypad.
Quick Value Keys: store/recall up to four frequently used resistance values with one touch. User-definable. 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 decade box to prevent possible damage.
Open Key: Conveniently 100% mechanically isolate the ohmSOURCE from the application with the touch of a key.
Increment Value Setting Change resistance by user-defined increments or select standard resistance values (1%, 5%, 10%)
Automatic Eliminates Residual Resistance - the OS-260 residual resistance is automatically factored out in output resistance value
Sensor simulation dual display operation being one of the key features, once programmed for your sensor of choice the unit of measure along with the resistance is viewed simultaneously on the graphic screen: Platinum Resistive Temperature Devices (RTD, PRTD), Negative temperature coefficient (NTC) Thermistors, Conductivity, Strain gauges, Potentiometric sensors (position, level)
