20 26 ! Differential Voltage Probe, 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. ! SAFETY PRECAUTIONS Warning, Risk of Electric Shock, Respect the max input voltages DP-30HS: 1.Max differential voltage: 65V (DC + AC peak) or

23 V RMS 2.Max voltage between each input terminal and ground:

600 V RMS DP-40LV: 1.Max differential voltage: 650V (DC + AC peak) or

230 V RMS 2.Max voltage between each input terminal and ground:

600 V RMS Do not use the probe in damp environment or where there is risk of explosion. Do not use the probe with its case open. Disconnect the inputs and outputs of the probe before opening the case. ! TO ORDER Differential Voltage Probe and Accessories: An Insulated BNC/BNC lead and two ψ4 mm, length

3 inches. Supplied a Adapter preset

9 V DC (115 V or

230 V)

2 x high voltage IC clips

2 x Banana to Banana high voltage plug

2 x Alligator plug DP-30HS Differential Probe (High Sensitivity Model) DP-30HS HIGH SENSITYVITY DIFFERENTIAL PROBE 1. FEATURES The DP-30 differential voltage probe provides a safety means of measuring floating potentials for all models of oscilloscopes incomplete safety. It converts the high differential voltage (Q 65V peak) into a low voltage (Q 7.0V) 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-30, and expand the measuring ranges. From DMM can observe more exact measured testing voltage. (Oscilloscope accuracy is 3%, and DMM is

10 times). 2. SPECIFICATIONS (1) Bandwidth: DC - to

30 MHz (-3 dB) for x 2, x

10 DC - to

15 MHz (for attenuation x 1) (2) Attenuation: x 1, x 2, or x

10 (3) Accuracy: +/- 2% (4) Voltage Input Ranges (DC + AC peak to peak) Q +/- 6.5 V for x 1, (i.e about 2.3 V RMS or DC) Q +/-

13 V for x 2, (i.e about 4.6 V RMS or DC) Q +/-

65 V for x 10, (i.e about

23 V RMS or DC) (5) Permitted Max Input Voltage Max differential voltage:

65 V (DC + AC peak to peak) Max voltage between each input terminal and ground:

600 V RMS
