Measuring; Selection Of Measuring Inputs - VOLTCRAFT LCR-300 Operating Instructions Manual

8. MEASURING

Do not exceed the maximum permitted input values. Do not touch any circuits or
parts of circuits if they may be subject to voltages higher than 25 V ACrms or 35 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!
During measuring, do not grip beyond the tangible grip range markings present on
the measuring prods.
Measuring is only permitted when the housing and battery compartment is 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 de-
scribed in detail in chapter 7.7. Calibration.
8.1. SELECTION OF THE MEASURING INPUTS
There are two options for connecting components to the measuring device. Via the integrated terminal
contacts or the 4-conductor measuring terminals. Both inputs are connected and must only be used
separately.
Observe that the plug "OPEN" (18) is always plugged in to
insulate the integrated measuring contacts in measuring line
operation if using measuring operation with the 4-conductor
measuring terminals. This plug prevents potential negative infl u-
ence of the second measuring input.
Connect the plugs of the red measuring glin4e to the sockets
"HPOT" and "HCUR" and their should to the socket "GUARD".
Connect the plugs of the black measuring line to the sockets
"LPOT" and "LCUR" and their should to the socket "GUARD".
Always remove the measuring lines in measuring operation with
the integrated terminal contacts. They can negatively infl uence
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.
