General Safety Summary
Please review the following safety precautions carefully before putting the
instrument into operation so as to avoid any personal injury or damage to the
instrument and any product connected to it. To prevent potential hazards, please
use the instrument only specified by this manual.
Use Proper Power Cord.
Only the power cor d desig ned fo r the ins trument and authorized for us e within the
local country could be used.
Ground the Instrument.
The instrument is grounded through the Protective Earth lead of the power cord.
To avoid electric shock, it is essential to connect the earth terminal of the power
cord to the Protective Earth terminal before connecting any inputs or outputs.
Connect the Probe Correctly.
If a probe is used, do not connect the ground lead to high voltage since it has
isobaric electric potential as the ground.
Observe All Terminal Ratings.
To avoid fir e or sh ock hazard, observe all ratings and markers on the instrument
and check your manual for more information about ratings before connecting the
instrument.
Use Proper Overvoltage Protection.
Make sure that no overvoltage (such as that caused by a thunderstorm) can re ach
the product, or else th e op erator might be exposed to the danger of electrical
shock.
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.

M300 is equipped with the DMM module power fuse (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) Select a proper voltage through the voltage selector.
4) Disassemble the fuse cap and fuse.
5) Replace a specified fuse and install the fuse cap.
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] Mixed In terface (Male)
This interface is 25-pin male interface. You can convert this interface into two
9-pin interfaces using the Mixed Interface Convert Cable (accessory). This
breakout cable consists of a 9-pin male in terface us ed as a standard RS232
interface and another 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 th e figure below, pin 1 to pin 4 are use d 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 7μs pulse width each time the
measurement is completed. The output rate is dependent upon the actual
measurement rate. The maximum output rate is 1000 times per second.
In external trigger mode, Pin 6 accepts external trigger signal. The trigger can
have a pulse width equal to or greater than 2μs with specified edge. To
configure, press Config , select “External” trigger mode and select “Rising” or

make sure the pulse period is larger than 100μs.
8 GPIB
The M300 c onforms t o the IEEE-488.2 standar d. Via this interface, the M300 can
be controlled remotely via a PC with a GPIB interface.
9 Power Socket
The 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.
10 Power Fuse
The specification of the fuse of M300 is AC 250V T3.15 A. If a new fuse is
required, please refer to “To Replace the Fuse”.
Please use the specif ied power fuse and make sure that the fuse

Power On Inspection
1 Connect the power
(1) Adjust the power voltage selector at the rear panel according to the power
supply volta ge. M300 supports two types of AC power. If your supply
voltage is in the range of 115*(100%-10%) V and115*(1 00%+10%) V,
please select 115 and if it is in the ran ge of 230 *(1 00%-10%) V and
230*(100%+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
1) Check whether the power is correctly connected.
2) Check whether the power key at the front panel is really on.
3) Check whether the power fuse is burned out. If the fuse needs to be
changed, use the specified fuse.
4) Check whether the correct power voltage is selected. Please select the
proper power voltage according to the power supply voltage.
5) Restart the instrument after f inishing the above inspections. If it still does
not work correctly, please contact RIGOL.
