2. General Safety Summary | |
|
|
¡@¡@Review the following safety precautions to avoid injury and prevent damage to this probe or any products that connected to it.
|
|
|
Observe Maximum Working Voltage |
|
|
¡@To avoid any injury, do not use the probe under the condition that the voltage between either input lead or earth is above 40Vrms CAT I. This voltage rating applies to 1/10 setting.
|
|
|
Must be Grounded |
|
|
¡@This probe is grounded with the shell of BNC connector and an auxiliary grounding terminal, through the grounding conductor of the power cord of the measurement instrument.
¡@Before making connections to the input leads of this probe, ensure that the output BNC connector is attached to the BNC connector of the measurement instrument and the auxiliary grounding terminal is connected to a proper ground, while the measurement instrument is properly grounded.
|
|
|
Do Not Operate Without Covers |
|
|
|
To avoid electric shock or fire hazard, do not operate this
probe with covers removed.
|
|
|
Do Not Operate in Wet/Damp Conditions |
|
|
|
¡@To avoid electric shock, do not operate this
probe in wet of damp conditions.
|
|
|
Do Not Operate in Explosive
Atmosphere |
|
|
|
¡@To avoid injury or fire hazard, do not operate
this probe in an explosive atmosphere.
|
|
|
Avoid Exposed Circuitry |
|
|
|
¡@To avoid injury, remove jewelry such as rings,
watches, and other metallic objects. Do not touch exposed connections
and components when power is present.
|
|
|
Use Proper Power Source |
|
|
|
¡@To ensure this probe function well, use a 9V cells or regulated 15VDC/100mA mains adaptor or power lead. Do not operate this probe from a power source that applies more than the voltage specified.
|
|
|
Do Not Operated With Suspected
Failures |
|
|
|
¡@If you suspect there is damage to this probe,
have it inspected by qualified service personnel.
|

|
3. Description |
|
|
|
¡@By enabling conventional oscilloscopes to display and measure in-circuit waveforms that are inherently differential signals, the differential probe extends the measurement capability of oscilloscopes in digital communication and high speed digital circuits.
|
|
|
|
|
|
|
4. Installation |
|
|
|
¡@a. Simply plug-in the BNC output connector to the vertical input of a general purposed oscilloscope or other measurement instrument, and connects the auxiliary grounding terminal to a proper ground. The measurement instrument must have a ground referenced.
¡@b. Connect an appropriate power source to this probe and then turn it on. |
|
|
|
¡@
|
WARNING. To protect against electric shock,
use only the accessory supplied with this differential probe.
|
|
|
|
|
|
¡@c. Using the appropriate probe accessories, connect the inputs to the circuits under measurement. |
|
| |
|
|
|
|
|
¡@
|
CAUTION. This probe is to carry out differential
measurement between two points on the circuit under measurement.This
probe is not for electrically insulating the circuit under
measurement and the measuring instrument.
|
|
|
|
|

¡@* Voltage limit is the lesser of the DC+Peak AC and RMS values..
¡@** a. The supplied voltage must be less than 16V and greater than 3.3V, otherwise the probe could be damaged or can¡¦t be operated properly.
¡@ b. For wrong polarity of power sources, a built-in circuit will protect the probe and no danger or damage will occur.
¡@ c. When the voltage of the cells become too low, the power indicator on the panel will change its color and then distinguish.

9. Inspection Procedure |
|
|
|
¡@a. Connect the BNC output connector to the
vertical input of a general purposed oscilloscope. |
|
|
|
¡@b. Connect AC mains adaptor to this probe and then turn it on. |
|
|
|
¡@c. Set the oscilloscope input coupling to DC and
the 0.5V/div. Center the trace on the display. |
|
|
|
¡@d.d. Connect the inputs of the probe to a sine-wave signal source of 100KHz and 10Vp-p. |
|
|
|
¡@e. Then, a 100kHz square-wave of 1Vp-p amplitude
will be displayed on the screen of the oscilloscope and this means
the probe is working properly. |
