The instrument furnishes a variety of prevision voltages with switched output ranges including 1.0, 1.018 + ΔE, 10.0 and ΔE volts. Delta E (ΔE) provides a variable output of 0 through 999 µV which is either added to the voltage of a standard cell transfer or may be used directly as a low-level, stable direct voltage source.\u003c\/div\u003e\n\u003ch4\u003e\u003cstrong\u003eKey Specifications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eOutput Ranges: 10V, 1V, 10018 + ΔE, 1.019 + ΔE, ΔE\u003c\/li\u003e\n\u003cli\u003eOutput Protection: The output may be shorted indefinitely without damage to instrument.\u003c\/li\u003e\n\u003cli\u003eLine Regulation: \u0026lt;1 ppm for ±10% line voltage variation\u003c\/li\u003e\n\u003cli\u003eRipple \u0026amp; Noise: \u0026lt;1 ppm peak-to-peak 0 to 1 Hz, \u0026lt;20µV rms 1 Hz to 1 MHz, except \u0026lt;70µV rms at 10V output\u003c\/li\u003e\n\u003cli\u003eIsolation: Output may be floated up to 500 dV between chassis ground and guard\u003c\/li\u003e\n\u003cli\u003eTemperature: 0°C to 55°C, operating\u003c\/li\u003e\n\u003cli\u003eSize: 8.8 cm H x 10.7 cm W x 30.4 cm D (3.5 in H x 4.5 in W x 12 in D)\u003c\/li\u003e\n\u003cli\u003eWeight: 2.26 kg (5 lb)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"TSD Electronic Store","offers":[{"title":"Default Title","offer_id":53248458752343,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/9389\/0135\/files\/FLUKE731B.jpg?v=1775366492","url":"https:\/\/www.tsdwelltest.com\/products\/used-fluke-dc-reference-standard","provider":"TSD Welltest Solution","version":"1.0","type":"link"}
