5. DMM Module Power Fuse
The AC power supply from the power socket is divided into two paths with one
for the DMM module and the other for other circuits except the DMM module.
M300 is equipped with the DMM module power fuse (its specification is AC 250V
T250 mA). To replace the fuse, refer to the method below.
1) Turn off the instrument and remove the power cord.
2) Press down the fuse cover using a straight screw driver and rotate
clockwise.
3) Disassemble the fuse cap and fuse.
4) Replace a specified fuse and install the fuse cap.
CAUTION
Please use the specified fuse to avoid electric shock and fire.
6. Voltage Selector
M300 supports two kinds of AC voltages (115 V and 230 V). Please select the
proper voltage scale according to the AC power used.
7. RS-232/Alarms/Ext Trig Mix Interface (Male)
This interface is 25-pin male interface. You can convert this interface into two
9-pin interfaces using the Mix Interface Convert Cable (accessory); wherein, one
is a 9-pin male interface used as a standard RS232 interface and the other is a
9-pin female interface used for alarm output, external trigger signal input, etc.
RS232: via this interface, M300 can communicate with the PC and you can
control the instrument remotely via the PC.
RS232 Interface
Alarms/Ext Trig: as shown in the figure below, pin 1 to pin 4 is used to
output TTL pulse when an alarm is generated in the corresponding alarm
channel. Pin 6 is used to receive external trigger signal. When an external
digital multimeter is connected for measurement, pin 5 and pin 6 are used
together to control the measurement.

Alarms/Ext Trig Interface
Note:
The Pin 5 outputs a TTL negative pulse with about 2μs pulse width each time the
measurement is completed. The output rate is dependent upon the actual
measurement rate and 2500 times per second at most.
In external trigger mode, when the Pin 6 accepts external trigger signal (which
pulse width is equal to or greater than 2μs) with specified edge (press Config ,
select “External” trigger mode and select “Rising” or “Falling” in Edge item), the
instrument triggers. If the external trigger signal is continuous pulse, please
make sure the pulse period is larger than 100μs.
8. GPIB
M300 conforms to the IEEE-488.2 standard. Via this interface, M300 can
communicate with the PC and you can control the instrument remotely via the
PC.
9. Power Socket
M300 can accept two kinds of AC power supplies. Use the power cord provided
in the accessories to connect the AC power supply to the instrument via this
socket.
CAUTION
Before connecting the AC power supply, select the correct voltage
scale using the voltage selector.

Power On and Inspection
1. Connect the power
1) Adjust the power voltage selector at the rear panel according to the power
supply voltage. M300 supports two types of AC power: if your supply
voltage is in the range of 115*(1-10%) V and115*(1+10%) V, please select
115 and if it is in the range of 230*(1-10%) V and 230*(1+10%) V, please
select 230.
2) Connect the instrument to AC power using the power cord provided in the
accessories.
2. Start the instrument
Press the power key at the front panel and the instrument starts.
After the instrument starts, it checks the modules. This process would take
several to dozens of seconds according to the number of modules inserted.
During this process, user operation is forbidden.
3. Check the instrument following the steps below if the instrument
does not start normally
Check whether the power is correctly connected.
Check whether the power key at the front panel is really on.
Check whether the power fuse is burned out. If the fuse needs to be
changed, use the specified fuse.
Check whether the correct power voltage is selected. Please select the
proper power voltage according to the power supply voltage.
Restart the instrument after finishing the above inspections. If it still does
not work correctly, please contact RIGOL.
