YOKOGAWA DL850E User Manual

In Using the High Voltage Differential Probes
Be sure to connect the ground lead of the differential probe (700924, 700925, 701926) to
the functional grounding terminal on the right side panel of the DL850E/DL850EV before
connecting to the measurement target. Not doing so may cause high voltage to appear in the
BNC connector of the differential probe.
Maximum Input Voltages and Maximum Allowable Common Mode Voltages for the Modules
Applying a voltage exceeding the value indicated below may damage the input section. If the
frequency is above 1 kHz, damage may occur even when the voltage is below this value.
