1000A Precision Current Shunt Operation Manual 1
Chapter 1 General information
1-1. Introduction
The model 1000A precision current shunt is a precision AC/DC shunt. It incorporates five shunt
ranges from 1Ω, 0.1Ω, 0.01Ω, 0.001Ω to 0.0001Ω. The AC/DC measuring current range from
200mA, 2A, 20A, 200A to 1000A full scale and a built-in 5 1/2 digit precision AC/DC current meter
with AUTO-ZERO and AUTO-RANGE function. Each shunt range has its own a select key
provides access to the voltage output terminals of each shunt resistor. A single set of binding post
conveniently provides output voltage to the measuring voltmeter.
The compliance voltage of the shunt is less than 0.2 volts at full scale for each range except the
1000 Ampere range which has a compliance voltage of 0.1 volts. The shunt is a highly stable
AC/DC resistor connected in a four-terminal non-inductive configuration for each range except the
1000A range.
1-2. Specifications
SHUNT all types are 4 terminal networks with calibration adjustments for each network.

Chapter 2 Installation
2-1 Check line voltage
The 1000A precision current shunt can be operated from a 100/115 or 200/230Vac input as
indicated on the label on the rear panel. The input is switchable so please make sure that the
switch is set correctly for your nominal mains input before turning on the mains power. The
procedure below details how to change the switch position:
2.1.1 With the 1000A power OFF, disconnect the power cord.
2.1.2 Refer the drawing on the rear panel in Fig 2-1, set the switches to the
Proper voltage as described in the following:
a. Set Switch to 100V/115V for 115Vac line voltage
b. Set Switch to 200V/230V for 230Vac line voltage
Note: 100Vac and 200Vac is used for Japan only (Option)
Fig 2-1 SET OF SWITCH
2-2 Input Fuse
This product is fitted with a mains input fuse. If it needs to be replaced please adhere to the
Following procedure.
BEFORE replacing the fuse you must switch off the unit and mains power outlet and
disconnect the plug of the AC Power cable from the input socket of the 1000A.

1000A Precision Current Shunt Operation Manual 5
2.3.1 Check the rating of the mains input fuse. Replace only with the correct
Type and rating.
For 100V/115Vac Input use T0.5A/250V (5*20mm),
For 200V/230Vac Input use T0.5A/250V (5*20mm)
2.3.2 The AC line fuse is located below the AC line socket (see Fig 2-2). Use
A small screwdriver to remove the fuse holder. Replace the failed fuse
With the appropriate type and rating according to your mains voltage.
(See Table 1-1)
2.3.3 Refit the fuse holder and connect the power cord.
Fig 2-2 FUSE RECEPTACLE
2-3 Grounding requirements
SHOCK HAZARD
The unit is grounded via the AC Input. It must be ensured that the correct mains lead with earth
pin is used. Correct grounding of your electrical system infrastructure according to national
standards must also be observed.
If prior to exchanging the fuse, there is any abnormal noise or odour do not use the
unit. Please inform your local sales office to organise repair of the 1000A.
To avoid the risk of fire or electronic shock the fuse must only be replaced with same
type and rating as the original. Any replacement fuse used should meet your national
safety standards. Any use of improper fuse or shorting the Fuse holder would be
extremely dangerous and would be strictly prohibited.

3.3.3. AC/DC Select key
Pressing the "AC/DC" key on the 1000A current Shunt, the appropriate LCD will
Illuminate according to the operating AC or DC mode is selected.
3.3.4. Current measurements
The 1000A use a four terminal current shunt configuration. Two terminals

1000A Precision Current Shunt Operation Manual 13
(CURRENT INPUT) are connecting the load in series with the panel terminals of
the appropriate current shunt. Note the maximum current limit label on the panel.
The RANGE selector key-switch is used to select the voltage sense terminals
(VOLTAGE OUTPUT) and the 5 1/2 digit precision current meter. The VOLTAGE
OUTPUT sense terminal and the 5 1/2 digit precision current meter are connected
directly across the calibration adjustment divider of the shunt resistor selected by
the RANGE key-switch.
3.3.5. Output
To measuring the load current can〝direct reading〞from 5 1/2 digit precision
AC/DC current meter in normally application. For the higher accuracy & resolution
Application, the OUTPUT voltage can be measured with a measuring device
(Thermal transfer standard, 6 1/2) precision DVM, etc).
It is not necessary that a load connected to one range be disconnected when
connecting a load to another range as the range key-switch isolates the shunts
from one another.
3.3.6. Setting GPIB Address
Set the GPIB address you must press the AC/DC key three second. The
LCD will display the current address.
Note: GPIB initial value of 06
Press 2A (UP), 20A (down) buttons to adjust the GPIB address 1 to 31.
Once the required address is reached press AC/DC key to save the New
Address and return to the normal screen.
