P5122100X ProbeThe P5122Probe is a high voltage probe with 100X attenuation and a compensation range of 10to 25pF.The probe is designed for use with Tektronix TPS2000and THS3000series floating oscilloscopes with high input impedance (1M Ω).The probe has no user-or Tektronix-serviceableparts.WARNING.The reference contact ring (see below)is always the same voltage as the reference lead.To avoid arc flash,always ensure the insulation sleeve or hook tip is installed to cover the reference contactring.Connecting the Probe to the OscilloscopeConnect the probe as shown in the illustrationsbelow.Compensating the ProbeDue to variations in oscilloscope input characteristics,the low-frequency compensation of the probe may need adjustment after moving the probe from one oscilloscope channel to another.If a 1kHz calibrated square wave displayed at 1ms/division shows signi ficant differences between the leading and trailing edges,perform the following steps to optimize low-frequency compensation:1.Connect the probe to the oscilloscope channel that you plan to use for your measurements.2.Connect the probe to the probe compensation output terminals on the oscilloscope frontpanel.WARNING.To avoid electric shock,only connect to the Probe Comp signal on the oscilloscope when making this adjustment.3.Depress the locking pin inside the protective sleeve.4.Turn the sleeve and the cable end until the adjustment is visible through theopening.5.Push AUTOSET or otherwise adjust your oscilloscope to display a stable waveform.6.Adjust the trimmer in the probe until you see a perfectly flat-top square wave on the display.(Seeillustration.)WARNING.To avoid electric shock,only use the insulated adjustment tool when making compensation adjustments.7.Turn the sleeve back and lock the sleeve inplace.WARNING.To avoid electric shock,ensure that the sleeve is locked in the closed position after making compensation adjustments.Connecting the Probe to the CircuitUse the standard accessories included with the probe to connect to your circuit.(See Table1.)WARNING.To avoid electric shock when using the probe or accessories,keep fingers behind the finger guard of probe body &accessories (as shown).To reduce risk of shock,when using the probe on floating measurements,ensure the reference lead accessories are fully mated before connecting the probe to the circuit under test.Standard AccessoriesThe standard accessories included with the probe can be reordered as a kit.The kit includes one of each item shown below.Order Tektronix part number 020-3046-00.Table 1:Probe accessories kitItemDescription Hook tip 1.Press onto probe tip2.Squeeze the hook tip to extend the conductive hook3.Clamp hook ontoconductor Reference lead,with hook clip

User’s Guide TESTEC High Voltage Probe TT-HVP 40This high voltage probe is designed to prevent accidental shock to the operator when properly used. This operating note must be read and understood prior to using the probe. Improper procedures or incorrect analysis of the measurement situation can result in serious shock.General InformationThe Testec High Voltage Probe TT HVP 40 is an accessory to be used with analog or digital multimeters having an input resistance of 10 M Ω. The Testec Model TT-HVP 40 is a 1000:1 divider which extends a voltmeter’s measurement capability to 40 kV dc/ 28 kV rms ac.SpecificationsMaximum Input Voltage Temperature CoefficientDC Voltage: 40kV Less than 200ppm/°CAC Voltage: (0 to 300 Hz) 28 kV RMSAccuracy Division RatioDC volts: 1000:1 when terminated in 10 M Ω ± 5 % (1 kV to 20 kV) 2000:1 when terminated in 1 M Ω ± 6 % (20 kV to 40 kV) AC Volts:± 5 % at 60 Hz Measurement Category I (CAT I)Other CharacteristicsInput Resistance Operating Temperature1000 M Ω 0 °C to +50 °CCable Length: Storage Temperature:1 meter -20 °C to +70 °CAltitude: HumidityUp to 4.6000 meters (15.000 ft) Up to 80 % relative humidity at +40 °CAC output derates with frequencyright shows typical AC accuracy.dBDC Hz 300WarningSafety Precautions • This high voltage probe must only be used by personnel who are trained, experienced, or otherwise qualified to recognize hazardous situations and who are trained in the safety precautions that are necessary to avoid possible injury when using such a device. • Do not work alone when working with high voltage circuits • For your own safety, inspect the probes for cracks and frayed or broken leads before each use. If defects are noted, DO NOT use the probe. • Hands, shoes, floor and work bench must be dry. Avoid making measurements under humid, damp or other environmental conditions that might effect the safety of the measurement situation. • It is advisable to turn the high voltage source off before connecting or disconnecting the probe. • The probe body should be kept clean and free of any conductive contamination. Refer to the section on cleaning. Operation • Connect the plugs to the volts [Hi] and com [Lo] terminals of your voltmeter • Select the desired voltage function and range; do not use autoranging • Whenever possible, turn the high voltage source off before making any connections • Connect the divider probe common lead (alligator clip) to a good earth ground or reliable chassis ground • Do not attempt to take measurements from sources where the chassis or return lead is not grounded• The ground lead is critical to the safe operation of the probe. Failure to make this connection when making high voltage measurements may result in personal injury or damage to the probe or volt-meter. This connection must always be made BEFORE the probe tip comes in contact with the high voltage and must not be removed until the probe tip has been removed from the high voltage source.• Do not connect the ground clip lead to the high voltage source for any reason.• Before turning the high voltage on, make sure that no part of your body is in contact with the device under test.• Measure the voltage remembering that the voltage being measured is 1000 times greater than the voltmeter reading.• Turn the high voltage off.• Disconnect the probe tip from the high voltage source BEFORE removing the ground clip lead.Cleaning• Clean only the exterior probe body and cables. Use a soft cotton cloth lightly moistened with a mild solution of detergent and water. Do not allow any portion of the probe to be submerged at anytime.• Dry the probe thoroughly before attempting to make voltage measurements.• Do not subject the probe to solvents or solvent fumes as these can cause deterioration of the probe body and cables.Testec Elektronik GmbH Phone +49 (0)69-943335-0 Westerbachstr. 58 Fax: +49 (0)69-943335-55D - 60489 Frankfurt www.testec.de Warning。
