IM CA11E-01E <1>
<6> MEASURE (measurement) / SOURCE (generation) selection switch
Selects MEASURE (measurement) or SOURCE (generation).
<7> Voltage input terminals
Used to measure a voltage range.
<8> Voltage output/current input and output terminals
Used for SOURCE mode (signal generation) in the voltage range, and for MEASURE mode
(measurement) and SOURCE mode (signal generation) in the current range.
<9> AC Adapter connection jack
Used to connect an AC adapter (optional).
<10> DIP switches
See Section 7, “Other Features.”
<11> Battery holder
Contains four AA-size batteries. See Section 3, “Replacing the Batteries.”
<12> Lead cables for measurement or generation
Used to connect the instrument to the device under measurement/generation.
3. Replacing Batteries
When the
+ -
mark is blinking on the display unit, the batteries are exhausted. Replace them
according to the following procedure:
<1> Check that the power is turned off (disconnect the lead cables).
<2> Slide off the cover at the back of the instrument.
<3> Replace all four batteries with new ones. Insert them according to the polarity directions
shown inside the holder.
<4> After replacing the batteries, return the cover to the original position.
■
Connecting the AC Power (optional)
Before connecting the AC power
Strictly observe the following warnings to avoid electrical shock or damage to the instrument.
WARNING
●
Do not use any AC adapter other than the dedicated AC adapter from Yokogawa.
●
Before connecting the power cord, check that the supply voltage matches the rated
voltage of the instrument.
●
Before connecting the power cord, check that the instrument's power key is OFF.
Connection procedure:
<1> Check that the [POWER] key of the instrument is off.
<2> Connect the AC adapter (optional) to the instrument's AC adapter connection jack. (Note that
unless the AC adapter is connected to the power outlet, the power cannot be turned on).
4. Turning the Power On/Off
■
Operating the POWER Key
When the instrument's power is off, pressing and holding the [POWER] key for more than 1 second
causes the power to be turned on. Pressing the key again causes it to be turned off.
When the power is turned on, the instrument starts a self-test and displays “CA11E.” Then the
features selected using the range selection rotary switch and the MEASURE/SOURCE selection
switch start functioning.
• For battery-driven operations, disconnect the AC adapter from the instrument.
■
Automatic Power Off
In the factory setting, all indications start blinking if the instrument has not been operated for about
9.5 minutes. Then, if the instrument is not operated for another 30 seconds, it automatically turns
off. To disable this automatic power off feature, see Section 7, “Other Features.”
If you wish to keep the instrument turned on after the indications start blinking, press the [POWER]
key (or any other key). This causes the blinking to return to normal lighting, without changing the
previous settings.
5. SOURCE (generation)
5.1 Connecting the Output Terminals
<1> Insert the plugs of the supplied lead cables into the output terminals of the instrument.
<2> Connect the clips on the other ends of the cables to the input terminals of the device under
generation.

CAUTION
●
Do not apply any voltages to the output terminals except for the 20 mA SINK range. If
voltage is applied mistakenly, the internal circuit may be damaged.
●
As the instrument is calibrated without the voltage drop of the lead cables, error due to
the resistance of the lead cables (approx. 0.1
Ω
for go and return) must be considered for
load current measurement.
5.2 Generating DC Current or DC Voltage
The instrument generates voltage or current at a specified value through the output terminals. In valid
ranges, terminal-to-terminal connection opens, and the display unit indicates “-nC-” and “OFF.”
1. Safety Precautions
When operating the instrument, strictly observe the precautions below to ensure its correct and safe
operation. If used other than as instructed in this manual, Yokogawa Meters & Instruments Corporation
is not liable for any damage that may result.
■
The following safety symbols are used on the instrument and in the manual:
Danger! Handle with care.
This symbol indicates that the operator must refer to an explanation in the User's Manual in
order to avoid risk of injury or death of personnel or damage to the instrument.
WARNING
Indicates a hazard that may result in the loss of life or serious injury of the user unless the
described instruction is abided by.
CAUTION
Indicates a hazard that may result in an injury to the user and/or physical damage to the
product or other equipment unless the described instruction is abided by.
NOTE
Indicates information that is essential for handling the instrument or, should be
noted in order to familiarize yourself with the instrument’s operating procedures and/or functions.
■
Damage to the instrument, personal injury or even death may result from electrical shock or
other factors. To avoid this, follow the precautions below:
WARNING
●
Use where gases may be present
Do not operate the instrument in a location where flammable or explosive gas/vapor present. It is
extremely hazardous to operate the instrument in such an atmosphere.
●
External connection
If necessary to touch a circuit to make an external connection, turn off the power to that circuit,
ensure there is no voltage, then perform the connection. When replacing the batteries, disconnect the
lead cables in advance.
●
Disassembly
Do not disassemble or remodel the instrument yourself. This needs to be done by our service
personnel.

using the selection switch <6>.
c. CAL
Lights up in the calibration mode.
d. 0/FS
Lights up or blinks when offset or full-scale adjustment is performed in the calibration mode.
e.
+ -
This mark indicates the battery's status. When lit, it indicates the batteries will soon need
replacing. When blinking, it indicates that they must be replaced (see Section 3, “Replacing the
Batteries”).
f. Main Seven Segment
Displays a measured value or an output value.
g. Sub Seven Segment
“SP” appears here when the sweep function (see Section 7, ”Other Features”) is selected in
SOURCE mode (signal generation). It also displays the lower two digits of a measured or an
output value in the calibration mode.
h. Displays the unit of the range selected.
i. OFF
In SOURCE mode (signal generation), it lights up when the output is turned off or when the
protective circuit is activated.
In MEASURE mode (measurement), it lights up only when the protective circuit is activated.
j. ON
It lights up when the output is turned on in SOURCE mode (signal generation).
<2> Output value setting keys
Sets an output value SOURCE mode (signal generation). The [
▲
]/[
▼
] keys are provided under the
lower four digits, whose values are increased or decreased in increments of 1. Carry of the digit is
applied to increasing the value (pressing the [
▲
] key) when it is 9. Borrow of the digit is applied to
decreasing the value (pressing the [
▼
] key) when it is 0.
For the 4-20 mA and 1-5 V ranges, see Subsection 5.2, “Generating DC current or DC voltage.”
<3> POWER key
Turns on/off the power supply. For more information, see Section 4, “Turning the Power On/Off.
<4> OUTPUT ON/OFF key
Turns the output on/off in SOURCE mode (signal generation). In MEASURE mode (measurement),
it returns measurement operation to normal status after the protective circuit is activated.
<5> Range selection rotary switch
Selects a range for SOURCE mode (signal generation) or MEASURE mode (measurement). Note
that the 4-20 mA and 1-5 V ranges are step output ranges in signal generation and are the same
as the 20 mA and 10 V ranges in measurement, respectively. For invalid ranges, terminal-to-
terminal connection becomes open, causing “-nC-” and “OFF” to appear on the display unit.
