TT-HVP 2739 High-Frequency High Voltage Probe
E-3
2. SAFETY 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.
• 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.
• This probe is designed for use within Measurement Cate-
gory I (CAT I) only. Do not use the probe for measurements
performed on circuits defined by any other measurement
category.
• When measuring voltage source is over DC 30KV or AC
20KV, this probe is NOT suitable for long time using. High
voltage source will have sparks in the air and cause high
voltage source regular circuit does not have time to respond.
This will have pulsed high voltage and which will cause this
probe over rating and damage the product.
Do not exceed 60 seconds of contact between the probe and
circuit-under-test when measuring voltages ≥30 kV DC or ≥
20 kV AC (RMS). TESTEC recommends that an interval of at
least 5 minutes be taken between measurements.
• Do not work alone when working with high voltage circuits!
• Hands, shoes, floor and work bench must be dry. Avoid
making measurements under humid, damp or other environ-
mental conditions that might affect the safety of the
measurement situation.
• The probe body should be kept clean and free of any con-
ductive contamination. Refer to the section on Cleaning.
• The probe is for indoor use only.
• If possible, always turn the high voltage source off before
connection or disconnection the probe.
