DifferentialVoltageProbe,
Read the instructions before using the instrument:
1. Must acquire a differential voltage probe & get the best service from
instrument.
2. Read carefully the USER MANUAL.
3. Respect the safety precautions.
SAFETYPRECAUTIONS

FEATURES:
The DP-35 differential voltage probe provides a safety means of
measuring floating potentials for all models of oscilloscopes incomplete
safety.
It converts the high differential voltage (≦1600 peak) into a low
voltage (≦8.0 V) with reference to the earth for display on the
oscilloscopes.
The BNC output is designed to operate on an input with an impedance
of 1 MΩ. It is 2 times of the 50 Ω.
Recommend to use PINTEK PL-10 with DP-35, and expand the
measuring ranges. From DMM can observe more exact measured
testing voltage. (Oscilloscope accuracy is 3%, and DMM is 10 times).
DP-35 is a design for high sensitivity module and high dynamic range.
Attenuation x10, x100 is multiple of 10, which is easy for calculation
without mistake. Maximum voltage is 1600Vp-p. It is for high sensitivity
as well as for high voltage.
SPECIFICATIONS:

≦1600 Vp-p for x 100, (i.e about 560 V RMS or 800 V DC)
(5) Permitted Max Input Voltage
Max differential voltage: 1600V (DC + AC peak to peak)
Max voltage between each input terminal and ground: 600 V RMS
(6) Input Impedance:

OPERATING PROCEDURE:
Connect to leads to the input and place the wire-grip on the circuit to be
tested.
Connect the probe to the oscilloscope with the insulated BNC/BNC
lead.
Adjust the vertical zero adjustment of the oscilloscope if necessary.
Select the attenuation ratio* and the vertical deviation of the
oscilloscope in accordance with the conversion table below.
NB: The POWER light must come on.
The conversion table gives the real vertical deviation.

50 m 5 0.5
20 m 2 0.2
10 m 1 0.1
5 m 0.5 50 m
2 m 0.2 20 m
[NOTE]
The real vertical deviation in V/div is equal to the attenuation factor
multiplied by the range of vertical deviation selected on the
oscilloscope. It will be doubled in the case of use of a 50 Ωload.
Example:
With the probe on factor x100, the oscilloscope on 0.5 V/div, the real
vertical deviation is 100 x 0.5 = 50 V/div.
With a 50Ωload on the input of the oscilloscope the deviation becomes
100 V/div.

EXT. POWER SOURCE:
Power consumption of the probe is about 300mA (ASW-01), thus it not
suit for battery, please use the accessory adapter only.
If there are any damage on the adaptor, please contact us and use the
adaptor supply by us only. If the input power over 9V DC will caused to
the probe hard damage.
MAINTENANCE:
For maintenance, only use specified spare parts.
The manufacturer can not be held responsible for any accident arising
following a repair made other than it’s after sales service or approved
repairers.
CLEANING:
This probe does not require any particular cleaning. If necessary, clean the
case with a cloth slightly moistened with soapy water.
WARRANTY:
Unless notified to the contrary, our instruments are guaranteed against any
manufacturing defect or material defect. They do not bear the specification
known as the safety specification. Our guarantee, which may not under any
circumstances exceed the amount of the invoiced price, goes no further
than the repair of our faulty equipment, carriage paid to our workshops.
REPAIR:
Maintenance, repairs under or out of guarantee. Please return to product to
your distributor.
