HScope HS5x2 Oscilloscopes User's Guide 4

1 Getting Started
This chapter describes the steps you take when using the oscilloscope for the first time.

 Inspect the Package Contents

 Power-On the Oscilloscope
 Connect Probes to the Oscilloscope
 Input a Waveform
 Use Autoscale & Basic Gesture
 Compensate Passive Probes / Attenuators

HScope HS5x2 Oscilloscopes User's Guide 5

Inspect the Package Contents
Inspect the shipping container for damage.
If your shipping container appears to be damaged, keep the shipping container or cushioning material until
you have inspected the contents of the shipment for completeness and have checked the oscilloscope
mechanically and electrically.

Verify that you received the following items and any optional accessories you may have ordered:
 HScope HS5x2 oscilloscope.
 USB OTG Cable (it may include micro-usb adapter).
 Oscilloscope probes (one for each analog input channel) are not included in the basic offer.

Power-On the Oscilloscope

Android Device  OS version: Android 7+, best with Android 9+
Requirements  RAM: 512KB, best with 4GB+
 Flash: at least 1GB free (for waveform saving).

App Installation You may install HScope app from Google Play Store or Huawei App Store. In the
app store just search for “HScope”.

To power-on the 1 Connect the USB cable to the rear of the oscilloscope, then to your Android
oscilloscope device. Route the power cord so that there is no pressure on the USB
connectors.
2 Check that the oscilloscope red LED is on.

Always use a grounded power cord. Do not defeat the power cord ground.

HScope HS5x2 Oscilloscopes User's Guide 6

Connect Probes to the Oscilloscope
1 Connect the oscilloscope probe to an oscilloscope channel BNC connector.
2 Connect the probe's retractable hook tip to the point of interest on the circuit or device under test. Be sure
to connect the probe ground lead to a ground point on the circuit.

CAUTION Maximum input voltage at analog inputs

 50Vpk for HS502
 230Vrms for 30s for HS512 MAX

CAUTION Do not float the probes ground

Defeating the ground connection and "floating" the probes ground will
probably result in inaccurate measurements and may also cause equipment
damage. If you need to measure between two live points, use a differential
probe with sufficient dynamic range.

WARNING Do not negate the protective action of the ground connection to the
oscilloscope. The oscilloscope must remain grounded through the probe
ground. Defeating the ground may creates an electric shock hazard
through the oscilloscope case or the Android device in user’s hands.

HScope HS5x2 Oscilloscopes User's Guide 7

Input a Waveform
The Probe Comp signal is used for compensating probes.
1 Connect an oscilloscope probe from channel 1 to the Probe Ref terminal on the back panel.

WARNING A voltage source should never be connected to the ground terminal of this
instrument. If, for any reason, the Protective Conductor Terminal is
disconnected or not functioning properly and a voltage source is
connected to the equipment's ground terminals, the entire chassis and
Android device will beat the voltage potential of the voltage source, and
the operator or bystanders could receive an electric shock.

HScope HS5x2 Oscilloscopes User's Guide 8

Use Autoscale & Basic Gesture
Autoscale automatically configure the screen to best display the input signals vertically.

1 Double tap on the center of the screen.

You should see a waveform on the oscilloscope's display similar to this:

X2

2 Pitch and zoom with 2 fingers to change vertical zoom or horizontal zoom (time scale) or both.

HScope HS5x2 Oscilloscopes User's Guide 9

3 Use one finger to scroll or move the view up and down. Or move the finger on the bottom bar to scroll
just left and right.

If you see the waveform, but the square wave is not shaped correctly as shown above, perform the procedure
under "Compensate Passive Probes".
If you do not see the waveform, make sure the probe is connected securely to the front panel channel input
BNC and to the Probe Ref terminal.

HScope HS5x2 Oscilloscopes User's Guide 10

Compensate Passive Probes / Attenuators
Each oscilloscope passive probe must be compensated to match the input characteristics of the oscilloscope
channel to which it is connected. A poorly compensated probe can introduce significant measurement errors.

NOTE If your probe has a configurable attenuation setting (like the P6100 probes do),
the 10:1 setting must be used for probe compensation.

1 Enable the channel to which the probe is connected (CH-1 or CH-2).

2 Input the Probe Ref signal.
3 Perform the autoscale
4 If necessary, use a nonmetallic tool (supplied with the probe) to adjust the trimmer capacitor on the probe
/ attenuator for the flattest pulse possible.

Perfectly compensated

Over compensated

Under compensated

5 Repeat the procedure for each probe.
