8000 SERIES OPERATION MANUAL 8000 Series Multimeter Introduction The 8000 series range of multimeters offer maximised capabilities from a highly accurate 4ppm / 9ppm advanced design. Utilising the precision electronics to their fullest extent, the 8000 Series provides high performance core functionality combined with advanced operation modes in a single instrument.
000 SERIES OPERATION MANUAL Accuracy And Functionality The 8000 Series multimeters are available in 2 accuracy grades - the 8081 / 8080 4ppm model and the 8071 of 9ppm model. The appearance of these units is the same, however the model is indicated on the front & rear panel and shown on the display on power up. Multi Product Multimeter Designed to provide an accurate cost effective portable instrument for the calibration of a wide range of signal sources including pressure, temperature and more.
8000 SERIES OPERATION MANUAL Multi Interface Support All functions and ranges of the series 8000 multimeter are fully programmable over the multiple interfaces. The support of RS232, USB and Ethernet saves the cost of fitting GPIB cards to the PC, and also allows easy connection to portable PC’s, reducing the set up time for on site calibration. GPIB is also available where use of this type of interface is already implemented. TRANSMILLE LTD.
8000 SERIES OPERATION MANUAL Preparing the Multimeter For Use Initial Inspection After shipment the multimeter should be inspected for any signs of external damage. Should external damage be found contact the carrier immediately. Do not connect a damaged instrument to the line power as this may result in internal damage. Please keep the original box as this can be used when returning the multimeter for service and recalibration.
8000 SERIES OPERATION MANUAL Positioning the Multimeter. The multimeter can be used free standing on a bench or mounted in a standard 19” rack enclosure. The multimeter can be operated at any angle, the two front feet have tilt legs for bench operation. A 2” (5cm) space behind the instrument is also required for line and interface connections. Minimum 2” (5cm) Clearance TRANSMILLE LTD.
8000 SERIES OPERATION MANUAL Rear Panel Connections and controls Connections on the rear panel are for Line Power via a 3 Pin IEC connector incorporating the Line fuse and on-off switch -note the mains inlet is filtered. The multiple interface connections are available including RS232, USB, GPIB and Ethernet (LAN) These interfaces are optically isolated from the multimeter intput. On 8081 units a set of rear panel terminals are fitted as standard, including voltage, current (to 1A) and a guard terminal.
8000 SERIES OPERATION MANUAL Setting and checking the Line Voltage. WARNING THE LINE POWER CORD MUST HAVE AN EARTH CONDUCTOR TO AVOID RISK OF SHOCK. THIS INSTRUMENT MUST BE CORRECTLY EARTHED. The multimeter has been designed to work from either 100-120 Volt line supply or 200 - 240 Volt line supply. Check Supply voltage as marked on the rear panel before connecting to power line. Connecting the multimeter to the wrong supply will cause internal damage to the instrument.

8000 SERIES OPERATION MANUAL Using the 8081 – Best measurement practice. The 8000 series DMM offers several easy to use features to help the user make high accuracy measurements. The following information gives advice on using these features and how to avoid common errors. Nulling or Zero It is always good measurement practice on DC Voltage, DC Current and Resistance ranges to ‘zero’ the range first before making a reading.
8000 SERIES OPERATION MANUAL Understanding thermal EMF voltages. Thermal EMF voltages are generated wherever there is a metal to metal junction, an electrical connection between two different metals. The voltage generated is dependant on the metals and the temperature of the junction. Voltages up to many 10’s of micro volts can easily be generated by a simple banana plug connection, each connection being effectively a thermocouple.
8000 SERIES OPERATION MANUAL Zeroing Current Ranges Current ranges are easily zeroed by simply open circuiting the terminals and nulling the range CURRENT TERMINALS LEFT OPEN CIRCUIT FOR CURRENT RANGE NULL Diagram : Current Null using open circuit terminals 2-Wire null method (all ranges) [Except Electrometer] The recommended method is to short together the ‘measurement’ end of the test leads and zeroing the DMM. Using this technique the resistance of the test leads will also be zeroed out.
