5. Measurement
WARNING
● In an application where the calibrator is used together with the supplied lead cables for measurement, the allowable voltage to ground of the input terminals is 300 V maximum. To avoid electrical shock, do NOT use the calibrator at any voltage exceeding the maximum voltage to ground.
● The allowable voltage to ground when the supplied terminal adapter is attached to the input terminals is 30 Vpeak maximum. To avoid electrical shock, do not use the terminal adapter for measuring any circuit voltage exceeding the maximum voltage to ground.
TIP
• With the key, you can hold the measured value.
• When no measurement needs to be made, turn off the MEASURE mode by pressing the key. The measured value shown on the LCD disappears and power to the internal measuring circuit is cut off. This strategy saves on battery power.
• The reading of a measured value is updated at approximately one-second intervals. If the input is overranged, the measured value on the LCD reads as - - - - -.
