Calibrateur multifonctions CX 1651
Manuel de l'utilisateur 167
ATTENTION
The input terminals of the built-in multimeter are floating. Maximum voltage between
the input terminals and the chassis is 15 Vpk. If this value is exceeded, the multimeter
can be damaged.
If the measurement range is exceeded, the calibrator displays an error message; input terminals are disconnected
only in the voltage and current measurement mode and remain connected in all other modes.
If 140-41 cable adapter is used, the signal to be measured is connected to U/I – COM terminals. COM is the
common terminal of the multimeter.
Connection of the multimeter when measuring the voltage, current and frequency using Opt. 140-41 cable
adapter
The multimeter allows the measurement of small DC voltages in the range of 0 to 2 V. 140-41 cable adapter is
required. The signal to be measured connects to Hu/+mV and Lu/-mV terminals. Lu/-mV is the common terminal
of the multimeter. To activate the measurement, select mVDC function mode using METER button in the
function menu and press INPUT to measure the input value.
Measurement of resistance or temperature using resistance temperature sensors
Resistance can only be measured using four-wire connection using Opt. 60. Opt. 60 cable ends with four bananas,
labeled Hi, Hu, Lu, Li. Their meaning is as follows:
• Hi current terminal H
• Hu voltage terminal H
• Lu voltage terminal L
• Li current terminal L
During the measurement of resistance or temperature using resistance temperature sensors, the rules applicable to
the four-wire connection must be observed.
