Measuring; Selection Of Measuring Inputs - VOLTCRAFT LCR-400 Mode D'emploi

9. MEaSuRINg

Do not exceed the maximum permitted input voltage. Do not touch any circuits or parts of circuits
if they may be subject to voltages higher than 33 V/aCrms or 70 V/DC! Danger to life!
Before measuring, check the connected measuring lines for damage such as, for example, cuts,
cracks or squeezing. Defective measuring lines must no longer be used! Never reach beyond the
noticeable grip area marks at the measuring prods during measurements.
Measuring is only permitted when the housing and battery compartment are closed. only the two
measuring lines that are required for measuring operation must be connected to the meter at any
time. Remove all measuring lines not required from the meter for safety reasons.
If "OL" (overload) appears on the display, you have exceeded the measuring range.
Perform calibration before any measuring series to warrant accuracy. Calibration is described in detail in
chapter 7.7. Calibration.
a) Selection of measuring inputs
There are three options for connecting components to the measuring device. via the integrated terminal contacts,
the 5-conductor SMD measuring tweezers or the two 4mm measuring sockets. Both inputs are connected and must
only be used separately.
Connect the plug of the SMD measuring tweezers to the terminal contacts. When plugging in, observe that the
polarity "HCUR" and "LCUR" as well as the shield "GUARD" must match the label of the terminal contacts.
Always remove the measuring lines in measuring operation with the integrated terminal contacts. They can nega-
tively influence the measuring result.
If you carry out a measurement, make sure that the measuring points you touch with the measuring prods are
free from dirt, oil, solderable lacquer or similar. Such circumstances can falsify the measured result.
