Calibrateur multifonctions CX 1651
* relative deviation of resistance (capacitance)
* uncertainty of set resistance (capacitance)
* total value of resistance (capacitance) if non-zero deviation is set
•
Set desired value of resistance (capacitance) or relative deviation. The value can be set using numeric
keyboard, potentiometer or cursor buttons. Simulated resistance (capacitance) is not yet connected to the
output terminals. The information section of the display shows the symbol which
the disconnection of output terminals.
•
Connect the object to be calibrated to the output terminals labeled Hi - Lo.
•
Press OUTPUT button.
•
Red LED is lit above the OUTPUT terminals to indicate the connection of simulated resistance (capacitance)
to the output terminals. The information section of the display shows the symbol
Simulated resistance (capacitance) is connected to output terminals.
Setting relative deviation
•
Keep pressing the center cursor button until [ _ _ _ _ _ _ _ ] symbols appear under the relative deviation
value (∆% = xx.xxxx %).
•
The value can be set using numeric keyboard, potentiometer or cursor buttons. Confirm the value by pressing
"%" display button or by pressing ENTER.
Limitations resulting from electronic simulation
Electronic simulation of resistance and capacitance allows setting of a wide range of values with accuracy
sufficient for calibration of common multimeters. Electronic simulation has the following limitations:
•
measurement current supplied by the multimeter to be calibrated must not exceed the value specified by the
calibrator's documentation. If the current is exceeded, the accuracy of simulated value is not guaranteed.
•
maximum peak voltage at Hi - Lo terminals supplied by the multimeter to be calibrated must not exceed
specified limits. If the test voltage is exceeded, calibrator disconnects output terminals. Overload message is
displayed on the display.
