High Precision Calibration Source For voltage, current and thermocouples upon request Application The precision calibration unit combines high accuracy, low drift, low noise and superior long-term stability with multiple functionality and simple operation. Ramps, ∆+/∆-, and multiple setpoint storage make the operation of the device easier for the user. For that reason the application possibilities are many: High precision current and voltage source ± 52 mA, ± 30 V Option: ± 22 mA, ± 60 V Precision simulation for all conventional thermocouple types (optional) Error limit 0.003 % Rdg. Standard with RS232 and IEEE488 interface, USB and Ethernet (optional) Current "SINK" Description It is possible to set current of ± 200 nA ... ± 52 mA, voltage of ± 1 µV ... ± 30 V and, optionally temperature setpoint value of 14 thermocouples types. The output value is fed back via the sense line to eliminate voltage drops across the measuring leads. The device has an adjustable current/voltage limitation. An external voltage divider of 1 up to 1:1000 can be considered ► Precise testing of thermocouple temperature measuring internally. instruments With the thermovoltage sourcing option you can enter °C, °F and K, the temperature scales ITS 90 or IPTS 68 and the ► Calibration of controllers, sensors, detection devices and comparison point mode constant/external. Furthermore, when other devices used in process control sourcing thermocouples a calibrated external comparison ► Open-loop process control with the aid of integrated point can be used, whereby the data for calibration in the ramp function device can be taken into consideration. DIGISTANT® model 4462 can be used both as a stand-alone Indication of the source value is carried out in large 12 mm table-top device, as well as in automatic, computer-assisted figures on an illuminated graphics-LCD. manufacturing and testing systems. The device can be operated both via the keyboard as well as the interface. ► Calibration of current and DC-voltage meters Technical changes reserved Latest updates of data sheet always under www.burster.com burster praezisionsmesstechnik gmbh & co kg .
