Safety Information
To ensure the safety operation, the following signs are used only as
specied in this instruction manual.
WARNING Indicates that the current operation does not comply with
correct instruction. Therefore causing potential hazards to the user or
instrument. Also indicates how to avoid such hazards.
! CAUTION Indicates that if the current operation does not comply with
correct instruction. Therefore causing potential hazards to the instrument.
Also indicates how to avoid incorrect operation.
NOTE Serves as a sign to remind the user that they must understand
the correct operation of the simulator and its characteristics.
To prevent the user and the instrument from electric shock and other
hazards, it is necessary to follow the following regulations:
Warning - WARNING
• Do not operate the instrument where ammable gas or explosive
gas or vapor are exposed. This is extremely dangerous
• Never apply more than 30V between any two terminals, or between any
terminal and ground
Caution - ! CAUTION
• The split case (top and bottom) is not to be removed, unless by
qualied technicians
• To clean the instrument, periodically wipe the case with a damp cloth
and mild detergent, do not use any corrosive solvents
Note - NOTE
• For optimal accuracy, allow the instrument to warm up 5 minutes
before operating
•
If the automatic reference-junction temperature compensation of the
instrument deviates from its designed accuracy, contact a
qualied REED technician

Operating Instructions
Power ON/OFF
Power-key operation
Press the Power ON/OFF button (#2 on page 6) to turn the instrument on.
Press this button again, holding for one second to turn the instrument off.
When the instrument is on, it will begin an internal self-diagnosis at which
time the full screen will be displayed (#1 on page 6). Once complete, the
instrument is ready to be used.
Automatic power-off
As a default the instrument will be set to automatically turn itself off after
10 minutes with button operation. To turn off this feature:
1) Turn the instrument off
2) Press the Power ON/OFF button (to display the full screen)
3) Press the RANG button (#7 on page 6) when the instrument is in
the maintenance state. AP-XX will display
4) Press the button (#9 on page 6) when AP-ON is displayed.
AP-OF will now be displayed, indicating that the automatic
power-off is not on
5) Press the Power ON/OFF button to exit the maintenance state and
turn the instrument off
Outputs
The output terminal of the instrument can produce DC voltages set by the
user or simulating resistance.
! CAUTION Do not apply any voltage to the output terminal during the
operation. If any improper voltage is applied to the output terminal, it will
cause damage to the internal circuit.
