Environment

 Location: Indoor, no direct sunlight, dust free,

almost non-conductive pollution (Note below)

 Relative Humidity: Full accuracy to 80% RH, at

40°C

 Altitude: < 2000m
 Temperature: 0°C to 50°C

(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. The instrument falls under
degree 2.

Pollution refers to “addition of foreign matter, solid, liquid, or

gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.

 Pollution degree 1: No pollution or only dry, non-conductive

pollution occurs. The pollution has no influence.

 Pollution degree 2: Normally only non-conductive pollution

occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.

 Pollution degree 3: Conductive pollution occurs, or dry, non-

conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.

Power cord for the United Kingdom

When using the instrument in the United Kingdom, make sure the
power cord meets the following safety instructions.

NOTE: This lead/appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:

As the colours of the wires in main leads may not correspond with
the coloured marking identified in your plug/appliance, proceed
as follows:

The wire which is coloured Green & Yellow must be connected to
the Earth terminal marked with either the letter E, the earth symbol

or coloured Green/Green & Yellow.

The wire which is coloured Blue must be connected to the terminal
which is marked with the letter N or coloured Blue or Black.

The wire which is coloured Brown must be connected to the
terminal marked with the letter L or P or coloured Brown or Red.

If in doubt, consult the instructions provided with the equipment
or contact the supplier.

This cable/appliance should be protected by a suitably rated and
approved HBC mains fuse: refer to the rating information on the
equipment and/or user instructions for details. As a guide, a cable
of 0.75mm2 should be protected by a 3A or 5A fuse. Larger
conductors would normally require 13A types, depending on the
connection method used.

Any exposed wiring from a cable, plug or connection that is
engaged in a live socket is extremely hazardous. If a cable or plug is
deemed hazardous, turn off the mains power and remove the cable,
any fuses and fuse assemblies. All hazardous wiring must be
immediately destroyed and replaced in accordance to the above
standard.

Background

There are 3 terminals for the 300A, 30A and
3A/300mA/30mA ranges, respectively.

The 300A range uses the rear panel terminals
and uses M8 crimped terminal cables.

The 30A range uses the 30A terminal and uses
M4 sized crimped terminal cables or banana
plugs.

The 3A input terminal uses standard banana
plugs (GW Instek part number GTL-105A). The
3A terminal supports 3A, 30mA and 300mA
ranges.

WARNING

Ensure any current or voltage sources are disabled
before connecting any cables to the PCS­1000/PCS-1000I.

Steps

1. Turn the power switch off.

Warning

Connecting equipment to the current monitor
that is not floating, such as a DSO, can interfere
with measurement results.

Background

There are two common ground loops that can
occur when using the PCS-1000 current
monitor output.

Power Supply Line Common Ground Loop:
If the power source of the circuit and the
device connected to the current monitor output
are both grounded, a ground loop is created as
there are two different return paths to earth.

Measurement Ground Loop: If there are two

different return paths to the circuit’s low

potential, a measurement ground loop is
created.

Crest Factor Table

Crest factor is the ratio of the peak signal amplitude to the RMS
value of the signal. It determines the accuracy of AC measurement.

If the crest factor is less than 3.0, voltage measurement will not
result in error due to dynamic range limitations at full scale.

If the crest factor is more than 3.0, it usually indicates an abnormal
waveform as seen from the below table.

OPERATION

Background

The current monitor is used to measure the
voltage drop across the shunt resistors
manually.

For the PCS-1000, the current monitor outputs
the full scale current input (for the selected
range) as a voltage of 0~300mV.

For the PCS-1000I, the current monitor outputs
the full scale current input (for the selected
range) as a voltage of 0 ~ 3V.

Compound

Two or more commands on
the same command line.
Compound commands are
separated with either a semi­colon (;) or a semi-colon and a
colon (;:).

A semi-colon is used to join
two related commands, with
the caveat that the last
command must begin at the
last node of the first
