calibration environment.
10.7.1 Resistometer Calibration
• Use a standard resistor resistant to wear from age and with
strong temperature performance.
• Use a resistor with four terminals, in order to prevent effects
due to the resistor lead lines.
• Be sure to assign resistor values in instruments of 1 kHz AC.
Using a coil resistor will result in high inductance. For this rea-
son, pure (DC) resistance will not equal effective resistance
(impedance; displayed on the instrument).
• Connect the instrument to the standard resistor as shown
below:
10.7 Calibration Procedure
To prevent damage to the instrument, do not input
voltage between the positive SOURCE and
SENSE terminals or between the negative
SOURCE and SENSE terminals. Also, do not con-
duct measurement when the instrument is turned
off.
