Derating curve Please review the following safety precautions to avoid injury and prevent damage The derating curve for absolute maximum input voltage is as follows: to this probe or any products that are connected to it. Observe maximum working voltage To avoid any injury, do not use the probe when the voltage between either input lead and earth is above 600 V RMS CAT I. 600 600 1000 Must be grounded 100 This probe is grounded with the shell of the BNC connector and an auxiliary 20 grounding terminal. 10 WARNING Before making connections to the input leads of this probe, ensure that its output lead is grounded. You may do this either by connecting the BNC shell to a 1 grounded measurement instrument, or by 1.E+06 1.E+07 1.E+08 connecting the auxiliary grounding terminal to a reliable ground point. Read the next paragraph for Frequency (Hz) further advice. You must verify that the probe is securely grounded before connecting the probe input leads. Some types of measuring instrument, such as a USB oscilloscope connected to a laptop, are unlikely to be grounded even if the laptop is powered 10. Test procedure from the mains. Bench-top oscilloscopes are usually grounded, but in some cases may have been isolated from ground. A USB oscilloscope connected to a desktop computer is usually grounded. In any case, do not assume that the measurement a. Connect the BNC output connector to the vertical input of a general-purpose oscilloscope. instrument is grounded. Always verify the ground connection for yourself before connecting the probe input leads. b. Connect an appropriate power source to this probe and then turn it on. c. Set the oscilloscope input coupling to DC and 1 V/div. Center the trace on the Use fused test prods if necessary display. d. Connect the inputs of the probe to power lines. If this probe is intended to use for measurements in circuits of INSTALLATION e. A 50 Hz / 60 Hz sine-wave of proper amplitude will be displayed on the screen CATEGORY III, it should incorporate with fused test prods. of the oscilloscope. This means the probe is working properly. Do not operate without covers 11. Cleaning To avoid electric shock or fire hazard, do not operate this probe with the covers Use a soft cloth to clean the probe, taking care not to cause damage. removed. a. Do not immerse the probe. b. Do not use abrasive cleaners. Do not operate in wet or damp conditions c. Do not use chemicals contains benzene or similar solvents. To avoid electric shock, do not operate this probe in wet or 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. 2 Copyright Pico Technology 2008 DO144-1 DO144-1 Copyright Pico Technology 2008 7 Voltage (V RMS)
