1000 SERIES OPERATION MANUAL
Accuracy and Functionality
The 1000 Series calibrators are available in a rugged portable case or a bench
case. A rack mounting option is also available.
True Multiproduct Calibration
Designed to provide an accurate cost effective portable instrument for the calibration
of multimeters, clamp meters, frequency meters and temperature meters.
Designed for use in the laboratory or portable onsite calibration. The fast warm up
time combined with the small case and low weight make the 1000 series calibrator
also ideal for onsite calibration. The USB interface allows direct connection to a
computer/laptop.
USB Interface
All functions and outputs of the series 1000 calibrator are fully programmable over
the USB interface. The use of the USB interface saves the cost of fitting GPIB cards
to the computer, and also allows easy connection to laptops, reducing the set up
time for on-site calibration.
Output Connection Indication
The output terminal configuration is designed to match the majority of multimeter
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 and an
LED indicator shows the active output(s).
TRANSMILLE LTD. Version 1.30 Page 7
1000 SERIES OPERATION MANUAL
Preparing The Calibrator For Use.
Initial inspection.
After shipment the calibrator 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
retain the original packaging; this should be used when returning the calibrator for
service and recalibration.
Before connecting to Line power, ensure that the input voltage of the calibrator
matches your supply voltage. For further information on verifying the input voltage,
please refer to Page 11
Lifting and Carrying the Calibrator
The calibrator weighs 9.5kg so can be carried by one person. (note: observe all
normal practices for health and safety when carrying). The calibrator should always
be placed down on a firm flat surface on its base feet. Avoid knocking or banging the
calibrator and always place down smoothly.
The 1000A, in the ruggedized case should always be transported with the lid closed
to protect the front panel of the instrument from accidental damage.
Warning: DO NOT DROP THE CALIBRATOR
This may cause internal damage which will not be covered under
warranty
TRANSMILLE LTD. Version 1.30 Page 8
1000 SERIES OPERATION MANUAL
Moveable ‘arms’ attached to
front pair of feet
Positioning the Calibrator
The 1000 series calibrator is available in a variety of different casings for use on
site, on a bench or in a rack.
Care should be taken when positioning the calibrator to ensure that items are not
placed against the cooling vents. Placing items against the cooling vents will affect
the performance of the calibrator and reduce the amount of time that the 10A output
will operate for before reaching thermal cut-out conditions (see Page 70)
When considering placement of the 1000A (in ruggedized casing), ensure that the
calibrator is placed on a flat, stable surface.
For bench-top use, the 1000B (bench top casing) is fitted with 4 non-slip feet. The
front pair of feet are fitted with moveable ‘arms’ that can be positioned to raise the
front of the calibrator to a more ergonomic position.

1000 SERIES OPERATION MANUAL
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 calibrator must be ordered with 100-120 Volt line supply or 220 - 240 Volt line
supply option. Check that the line voltage matches the configured voltage before
connecting the power to the instrument. The input voltage is indicated on the front
panel underneath the power switch.
Warning: Connecting the calibrator to the wrong supply will
cause internal damage to the instrument.
Power Line Inlet Fuse and rating
The power line inlet fuse is located directly below the power inlet within the voltage
selector housing. The correct fuse rating is 2A anti-surge (slow blow) for 230V
operation and 4A anti-surge (slow blow) for 110V operation.
Replacing the Power Line Fuse
In the event of the Power Line fuse being damaged, the fuse will need to be
replaced. This operation can be performed by the user.
TRANSMILLE LTD. Version 1.30 Page 11
1000 SERIES OPERATION MANUAL
Warning: Ensure Line Power has been disconnected from
the instrument before performing this procedure
Using a Flat Head screwdriver, insert the end of the screw driver into the recess on
the fuse holder. The screwdriver must be parallel to the front panel of the calibrator
Once the screwdriver is in the recess of the fuse holder, gently hinge the fuse holder
up (away from the front panel). Be careful not to damage the fuse holder by applying
too much force. The fuse holder will lift out, revealing the fuse. Check the fuse using
a continuity tester to ensure that the problem is the fuse. If the fuse is damaged,
replace the fuse with an anti-surge fuse of the recommended rating for the supply
voltage. Re-insert the fuse holder in the same orientation as it was removed.
TRANSMILLE LTD. Version 1.30 Page 12
1000 SERIES OPERATION MANUAL
Connecting to a computer
A USB cable (supplied) should be used to connect the calibrator to a USB port
on a computer.
Connection Details
Connection from calibrator to a computer :
The USB connection on the 1000 series calibrator is a Female type B connection.
Also supplied is a USB driver on CD :
For details on installing USB driver see appendix A.
TRANSMILLE LTD. Version 1.30 Page 13
1000 SERIES OPERATION MANUAL
Powering up the calibrator
After connecting line power, the calibrator can be switched on with the line power
switch above the mains inlet socket on the front panel.
The fan will start and the front panel display will illuminate indicating power. The
display will show a firmware version number and after a short delay, during which
time the processor performs a self-test of the instrument, the display will show an
output of 0.0000mV DC. The default start condition of the calibrator is as follows:
Output Status : Standby
Range : 100mV DC
Negative to Ground Enabled
Allow the calibrator to warm up for 20 minutes to obtain full accuracy; the fast start
feature of the calibrator will give approximately 90% of full specifications within 10
minutes. The calibrator has been designed to be powered up continuously and does
not need to be turned off when not in use.
If required, a control program (i.e. ProCal) can now be started on the computer; the
program will establish communication with the calibrator. If used with ProCal, the
stored value of the passive standards will be downloaded to the computer, and the
calibrator will indicate ‘ProCal Control’ on the screen when ProCal is started.
TRANSMILLE LTD. Version 1.30 Page 14
1000 SERIES OPERATION MANUAL
Output Connections
Warning: Risk of shock.
High voltages may be present on the output sockets.
Output sockets are 4mm safety type, the voltage pair contacts are low thermal gold
plated for minimum thermal EMF.
The 1000 series calibrator’s outputs have been designed to allow most multimeters
to be calibrated without changing connections. There are 4 sets of outputs:
1) Voltage, Resistance, Capacitance, Frequency.
2) Current to 1A.
3) High 10A Current.
4) Thermocouple Output
The Voltage and Current terminals share a single common terminal. This allows the
1000 series to connect directly to all inputs on typical multimeters without the need
for changing leads as below:
When an output terminal pair is not active they are completely open circuit and
isolated from the other outputs.
Note: When outputting resistance, capacitance and frequency the calibrator will use
the voltage output terminals.
TRANSMILLE LTD. Version 1.30 Page 15
1000 SERIES OPERATION MANUAL
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 1T 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 for ensuring accurate measurements, see accessories.
Warning: Under no circumstances should any voltage
be connected to the calibrator outputs*. The 1000 Series
calibrator outputs are protected with IGuard however we
advise to be vigilant against accidental connections
* Insulation testers up to 1000V may be connected when using the Insulation test functions
Output Overloads
If the calibrator is unable to drive the load then the output will be turned off and the
calibrator returned to standby mode. The message Standby will be displayed on
the front panel. The output will be automatically reset on setting the output again.

1000 SERIES OPERATION MANUAL
Front Panel Keyboard
The front panel of the 1000 Series Calibrator utilises a high quality custom rubber
keyboard with tactile feel buttons and integral display window. The front panel is
therefore sealed against the ingress of moisture and dirt enabling the calibrator to be
used in most working environments without risk of early failure of the operating
buttons. The front panel can easily be wiped clean with a soft cloth. Care should be
taken not scratch the display window. All graphics are ‘under printed’ making them
rugged and durable.
IMPORTANT NOTE
The front panel key buttons are for use with fingers only - do not press
the key with hard or sharp objects e.g. Ball-point pens, pencils,
screwdrivers etc. Repeated actions like this will almost certainly cause
the keyboard to fail. (This will not be covered under warranty). Care
should also be taken when transporting the instrument, do not place
test leads or other objects on top of the panel which may come into
contact with the display area and cause damage.
