General Safety Summary
Carefully read the following safety precautions to avoid personal
injury and prevent damage to the instrument or any products
connected to it. To avoid potential hazards, please use the
instrument as specified.
Only qualified technician should perform service procedures
Use Proper Power Line
Use only the special power line that is approved by the
local state.
Ground the Instrument
The instrument grounds through the protective terra conductor of
the power line. To avoid electric shock, the ground conductor must
be connected to the earth. Make sure the instrument is grounded
correctly before connecting its input or output terminals.
Connect the Signal Wire correctly
The potential of the signal wire is equal to the earth, so do not
connect the signal wire to a high voltage. Do not touch the exposed
contacts or components.
Look Over All Terminals’ Ratings
To avoid fire or electric shock, please look over all ratings and sign
instruction of the instrument. Before connecting the instrument,
please read the manual carefully to gain more information about the
ratings.
Not Operate with Suspected Failures
If you suspect that there is a damage of the instrument, please let a
qualified service personnel check it.

Avoid Circuit or Components Exposed
Do not touch exposed contacts or components when the power is
on
Do not Operate in /Damp Conditions
Do not Operate in an Explosive Atmosphere
Keep the Surface of the Instrument Clean and Dry
Float Measurement Safety
The instrument can be used to measure floating signal when using
battery power. Grounding terminals of the two channels should be
connected to the same reference voltage while measuring
dual-channel floating signal. To avoid hazards that may happen
during measurement, please read the following notices carefully.
Warning
Floating signal can not be higher than 30Vrms or 42Vpk.
Warning
To protect the instrument and other products connected to it, do
not connect it to grounding equipment (such as computer or
printer) through a USB cable while measuring floating signal.

General Care and Cleaning
Care:
Do not store or leave the instrument in direct sunshine for long
periods of time.
Notice:
To avoid damages to the instrument or probe, please do not
leave them in fog, liquid, or solvent.
Cleaning:
Please perform the following steps to clean the instrument and
probe regularly according to its operating conditions.
1. Disconnect the instrument from all power sources, and then
clean it with a soft cloth.
2. Clean the loose dust on the outside of the instrument and probe
with a soft cloth. When cleaning the LCD, take care to avoid
damaging or scratching.
Notice:
To avoid damages to the surface of the instrument and probe,
please do not use any corrosive liquid or chemical cleanser.
Make sure that the instrument is completely dry before
restarting it to avoid short circuits or personal injuries.
6

Installation of Battery
The instrument is not installed with battery. To complete the
installation, please operate as the following steps:
1. Remove the two screws on the battery cover using a screwdriver.
As shown in figure 1.
2. Pull out the supporting leg and remove the battery cover. As
shown in figure 2.
3. Place the battery in position and close the cover. As shown in
figure3.
4. Tighten the screws using a screwdriver and turn on the
instrument to check if it’s successfully installed.
Notices:
 Connect the battery cable lightly due to its anti-reverse design.
 If the instrument fails to startup after successful installation of
the battery, it is likely due to low battery power,
please charge the battery fully before installation.
 The battery must be charged once every three months.

Quick Start
General Inspection
1. Inspect the shipping container.
Keep the damaged shipping container or cushioning material
until the contents of the shipment have been completely
checked and the instrument has passed both electrical and
mechanical tests.
The consigner or carrier will be responsible for damages to the
instrument resulting from shipment.
2. Inspect the instrument.
If there are instruments found damaged, defective or failure in
electrical and mechanical tests, please contact us.
3. Check the accessories.
Please check the accessories according to the packing list. If the
accessories are incomplete or damaged, please contact your
sales representative.

Measurement Connection
Accessories of RSHS800 Handheld Digital Oscilloscope consist of a
power supply adapter, a probe adapter plug, a USB cable, two
multimeter probes and two oscilloscope probes. The acceptable AC
power supply is: 100~240V, 45~440Hz.

1. Oscilloscope Probe
Connect the probe to the instrument BNC, then connect the
grounding alligator clip to the grounding point and signal
compensation terminal of the probe adapter plug which is
connected to the BNC port of the instrument, this will supply a
square waveform for calibration
.

2. Power Adapter
Connect one end of the power adapter to power socket of the
instrument and another end to AC power for charging.
3. Multimeter Pens
Before connecting the multimeter pens, please select a
measurement parameter , and then plug respectively the
red and black pen to corresponding connector according to the
graphic cues displayed on the screen.

Power-on Inspection
When the handheld oscilloscope is charged, press the power
button on the front panel to boot up the scope. During the start-up
progress, the instrument performs a series of self-tests and
you could hear the sound of relay switching. After the self-test
completed, the welcome interface displays immediately.
13

Function Inspection
To check if the oscilloscope function system of the instrument is
working normally, please perform the following function inspection
steps:
1. Press the Power button to turn on the instrument and it switches
to scope function automatically after the power-on self test.
2. Connect the probe adapter plug to the USB port of the
instrument.
3. Connect the BNC end of the probe to the BNC connector of the
instrument.
4. Connect the alligator clip and probe of another end to the grounding
end and compensation signal output terminal of the adapter plug.
5. Press AUTO to display square waveforms with 1KHz frequency
and about 3V peak value in normal conditions as shown below:
6. Test channel 2 in the same method. If waveforms displayed do
not appear like waveforms above, please perform the “Probe
Compensation”.

Probe Compensation
It is necessary to properly compensate the probe at first use of it.
Non-compensated or inadequate compensated probe may cause
inaccurate measurement. The following steps are about probe
compensation:
1. Perform step 1, 2, 3 and 4 of “Function Inspection”.
2. Check the displayed waveforms and compare them with figure
below.
under compensated over
compensated correctly compensated
3. Use anonmetallic driver to adjust the low-frequency
compensation adjustment hole on the probe until the waveforms
change to be correct as the figure ”compensated correctly".
