Accuracy And Functionality
The 8000 Series multimeters are available in 2 accuracy grades - the 8081 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. The 8000 series multimeter is equally
suitable for use in the standards laboratory or for on site calibration work with a fast warm up time
combined with low weight and optional soft / hard carry cases. The multi –interface design allows
direct connection to desktop or laptop PCs via RS232, USB, GPIB or Ethernet.
Expandable Range of Pressure Modules
A range of pressure modules are available for support of pressure measurement up to 100 Bar
(optional pressure hand pump also available).

TRANSMILLE LTD. PAGE 8
Multi Interface Support : Available As Standard.
All functions and ranges of the series 8000 multimeter are fully programmable over the multi
interfaces fitted as standard. 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.
Output Connection
The input terminal configuration is designed to most input connections, e.g. volts/ohms, low current
and high current. Eliminating the need for lead changing during calibration. All outputs are isolated
when not in use, an LED indicator showing the active output pair.

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 which can be used when
returning the multimeter for service and recalibration.
Lifting and carrying the Multimeter
The multimeter can be carried easily by one person by supporting from underneath (note : observe
all normal practices for health and safety when carrying). A custom carry case with shoulder strap is
available if the multimeter is to be regularly transported - see options list. The multimeter should
always be placed down on a firm flat surface on its base feet. Avoid knocking or banging the
multimeter and always place down smoothly.
WARNING
DO NOT DROP THE MULTIMETER AS THIS MAY CAUSE INTERNAL DAMAGE.

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. To
change the line voltage it is necessary to remove the rear panel and rewire the transformer. The
multimeter will have been shipped wired for 110V operation for USA or 230V for Europe.

Powering up the multimeter
After connecting line power, the multimeter can be switched on with the line power switch above the
mains inlet socket on the rear panel.
The front panel displays will illuminate and indicate if the instrument is in evaluation mode for a
period of 5 seconds, giving the user a chance to unlock the instrument. The start-up sequence will
operate internal circuits indicating initial power up during which time the processor performs a self
test of the instrument - the display will then switch to measurement display mode.

Output Connections
WARNING
THE LINE POWER CORD MUST HAVE AN EARTH CONDUCTOR TO AVOID RISK
OF SHOCK. THIS INSTRUMENT MUST BE CORRECTLY EARTHED.
Input sockets are all 4mm safety type, the voltage pairs contacts are low thermal gold plated for
minimum thermal EMF.
The 8000 series multimeter inputs have been designed to allow instruments to be calibrated
minimising connection changes. There are 2 pairs of inputs, a high current input and a single guard
input terminal :
When an output terminal pair is not active they are completely open circuit and isolated from the
other outputs (note : a 30A shunt is permanently connected between the current negative and 30A
terminals). As only one pair is active at a time on (except on 4 wire ohms) they may be combined
together if required to match the input arrangement.
One example common configuration of a instrument’s inputs is a single common low with a voltage,
current and high current input. To match this to the multimeter, simply connect the 3 low outputs of
the multimeter together and connect the voltage, current & high current outputs to the appropriate
meters input . Note that when measuring ohms, the multimeter will use the voltage input terminals in
2 Wire mode.
A second example where the UUT instrument has separate voltage and current inputs, often using 4
wire ohms on both pairs. In this case simply connect the voltage and current outputs to the meter’s
inputs, the multimeter will use both the voltage and current pair on 4 wire ohms.

It is recommended that the voltage and low current leads be high quality screened cable with gold
plated 4mm plugs fitted. The cable must be able to withstand 1025 volts AC and have an insulation
resistance greater than 1 TOhm to avoid introducing any shunting effect on the high resistance
ranges.
Poor quality test leads will introduce noise, thermal emf and leakage errors on low voltage & current
ranges and also unstable readings on resistance and capacitance outputs (see measurement
techniques ). Special test leads are available from Transmille, see accessories.
WARNING
OBSERVE ALL MAXIMUM INPUT RATINGS WHEN PERFORMING MEASUREMENTS
The low output can be connected to line earth or allowed to float as selected.
It is recommended that the low is earthed which will help to reduce noise on high ohms and low
current. If allowed to float with respect to line earth the low must remain within 50 volts of line earth.
Outputs are opto-isolated from the interfaces
Input Overloads
If the multimeter is unable to measure the input due to over range, the display will indicate
OVER-RANGE .
