Beschreibung

The IET Labs OS-270 is an electronically controlled Resistance Box provides highly accurate and stable resistance values. The OS-270 features user-friendly interface, resistances of up to 24MΩ, power of up to 1W and two banana-to-alligator cables for convenient connection. The ohmSOURCE still offers many advanced features to ensure that it is practical for both laboratory and field applications. The residual resistance of the ohmSOURCE is automatically included in the output resistance value. To conserve power, the ohmSOURCE automatically shuts-OFF after 4 minutes of inactivity. It can easily calibrate the ohmSOURCE with a high-precision ohmmeter.                                                                                                                                                                                                                                                                                                              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.
Memory Keys: Store resistance values in up to 10 additional memory locations (0-9).
Translation Tables (Optional Software with USB cable required Part Number OS-91.001 Accessories): Up to 4 numeric tables allow conversion from your units to a resistance value. Each table holds up to 255 entries; each entry contains your value and an associated resistance value. Your entries represent any type of curve; RTD, thermistor, thermocouple, strain gauge
Current Limiter: Limits the amount of current passing through the decade box to prevent possible damage.
Open Key: Electrically isolate the ohmSOURCE connections 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 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 display: Platinum Resistive Temperature Devices (RTD, PRTD), Negative temperature coefficient (NTC) Thermistors, Conductivity, Strain gauges, Potentiometric sensors (position, level).
