Points for Attention During Use
――――――――――――――――――――――――
WARNIN
G
When a power supply from AC adapter terminal
on the unit, before turning on the power, make
sure that the voltage of the power supply being
used matches the supply voltage indicated on
the part of the AC adapter terminal on the unit.
If an attempt is made to use an improper supply
voltage particularly in excess of 13.2 VDC, there
is danger of damage to this unit and of life-
threatening risk to the operator.
The optional 9418-10 AC ADAPTER is
constructed so as to be connected to a ground
line via a grounded two cable power cord such
as the power cord that is supplied with the unit.
In order to avoid electric shock, connect the unit
to a properly grounded power supply socket
using the power cord provided. In addition, if
using a ground adapter, be absolutely sure to
connect the green ground wire which protrudes
from the adapter to a ground line.
P
oints for Attention During Use
In order to ensure safe operation and to
obtain maximum performance from the unit,
observe the cautions listed below.

vi
―――――――――――――――――――――――――――
Points for Attention During Use
――――――――――――――――――――――――
WARNIN
G
This unit is designed for safe operation only at
low voltage. Ensure that no more than 60 V is
present between any terminal and ground, and
that the potential difference between any two
terminals does not exceed 60 V. The unit
cannot be guaranteed in an overrange situation,
such as due to an inadvertent electric shock or
faulty insulation, and we cannot accept
responsibility for any consequences that might
occur from misuse.
The output terminals and the voltage and
current input terminals (terminals for the
standard resistor) are all isolated. Before
connecting the terminals, ensure that the device
being measured will not provide excessive
output to, or require excessive input from, the
terminals. The unit cannot be guaranteed in an
overrange situation, such as due to an
inadvertent electric shock or faulty insulation,
and we cannot accept responsibility for any
consequences that might occur from misuse.

vii

Points for Attention During Use
――――――――――――――――――――――――
WARNIN
G
If the battery voltage drops while the unit is
running off of battery power, the 7011 will
automatically switch off the power supply. Note
that if the unit is left in this state for an
extended period of time, the optional 9420
BATTERY PACK may be discharged too much.
If the battery is left in the battery compartment
for a long time, it may leak. Such leakage may
damage the unit, or cause an electrical hazard,
so please remove the battery if the unit is not to
be used for a long period.
CAUTIO
N
･Do not store or use the unit where it will be
exposed to direct sunlight, high temperature, high
humidity, or condensation. If exposed to such
conditions, the unit may be damaged, the insulation
may deteriorate, and the unit may no longer satisfy
its specifications.
･To avoid damage to the unit, do not subject the unit
to vibrations or shocks during transport or handling.
Be especially careful to avoid dropping the unit.

Points for Attention During Use
――――――――――――――――――――――――
CAUTIO
N
･If this unit is subject to shock or vibration, do not
make any connections to the terminals until each of
the display selections and measurement function
selections have been checked to ensure that no
damage has been sustained.
･Before generation or measurement, make sure of
the function position.
If current or voltage in excess of generation or
measurement range is input, the unit may be
damaged.
･If output is impossible when "ON" is displayed
which indicates outputting, set to "OFF" with
OUTPUT ON/OFF and set output to "ON" again.
･The case is not hermetically sealed for protection
against explosion, so do not use in a flammable
atmosphere.

.1 Product Overview
The compact 7011 DC SIGNAL SOURCE uses
LR6 alkaline batteries (optional 9420
BATTERY PACK or *9418-10 AC ADAPTER),
and can output DC voltage and current, and
thermocouple power equivalent to preset
temperature (K, E, J, T, R, S, B). In addition,
it can measure DC voltage, current and
temperature which are electric potentially
insulated from generation circuit.
This unit is intended primarily for the
maintenance of measurement
instrumentation systems and industrial
meters, and for testing electronic circuits and
machinery. It includes standard voltage and
current source functions suitable for use in
the research laboratory. The miniaturized
design makes it easily portable, and the
internal rechargeable battery power source
ensures long term operation by simply
recharging the battery in the field.

.2 Product Features
Generation and measurement of DC voltage
from -25.000 V to 25.000 V (minimum resolution
100 μV), and of DC current from -25.000 mA to
25.000 mA (minimum resolution 1 μA).
Generate seven types of thermocouples K, E,
J, T, R, S and B (JIS C 1602-1981) to a preset
temperature.
Temperature measurement from -25℃to 80℃with
optional accessory 9184 TEMPERATURE PROBE.
Bipolar output can be used for load current sink.
So loop testing in the instrumentation system
is possible.
The 7011 is provided with following monitor
functions: current when constant voltage
generates, voltage when constant current
generates, reference junction temperature
when thermoelectric power generates.
Up to 20 memories are available to each
function to store displayed settings for
different conditions. Memory contents can be
recalled and can be generated in autoscan.
Common alkaline batteries support use in
situations where AC power is not available.
The 9420 BATTERY PACK is available as an
option for rapid recharging with the *9418-10
(less than 2 hours for full recharge).
The optional *9418-10 allows continuous long-
term operation.
