24 V DC Power Supply
Connecting the Output Terminal
Connection Precautions
WARNING
The permitted maximum potential difference is 42 Vpeak and Cat II
for every I/O and earth terminal. However, the permitted maximum
potential difference between the negative 24 V OUT terminal and
the ground is 18 Vpeak. Never apply a voltage exceeding this
tolerance, or the measured object circuit or equipment may be
damaged and the operator injured.
CAUTION
• Do not apply a voltage to the 24 V DC output terminal externally,
or else the instrument may be damaged.
• If the 24 V DC output terminal is short-circuited or the load
current exceeds the range (24 to 30 mA), an error is displayed
and the 24 V DC power supply is turned off. In this case, remove
the cause of the short circuit or the overload completely and then
turn the 24 V DC power supply back on. Note that an overload
cannot be detected for the first 5 seconds or so after turning on
the 24 V DC power supply.
• When using batteries, continuous running of the instrument with
the load current of the 24 V DC power supply at more than 20
mA shortens the operable time extremely.
Connecting
1
Insert the plug of the measurement lead into the 24 V DC output terminal of the
instrument.
2
Pinch the 24 V DC terminals on the target device with the clips on the other side of
the lead.

Turning Output On and Off
1
Press the [24 V OUT].
[24 V OUT] appears on the screen and the 24 V DC power is supplied from the
output terminal.
2
To stop the 24 V DC power supply, press [24 V OUT] again.
[24 V OUT] disappears from the display.
Note
• If the 24 V DC power supply becomes overloaded, the power supply turns off automatically. To
continue supplying 24 V DC power, remove the cause of the overload and then press the [24 V
OUT] key again.
