Initial Inspection - Cal Test CT3681 User Manual

1 Introduction
1.1 Overview
Differential probes allow safe, accurate measurement between two
voltage points where neither point is referenced to ground. The
CT3681 and CT3683 both offer a 70 MHz bandwidth and can test up
to ±7 kV (DC + AC peak). Compatible with oscilloscopes from all major
manufacturers, the probes can be battery operated, powered by a
universal adapter (optional), or powered by USB power lead (optional)
if the oscilloscope is so equipped.

1.2 Initial Inspection

This probe is tested prior to shipment. It is therefore ready for
immediate use upon receipt. An initial physical inspection should be
made to ensure that no damage has been sustained during shipment.
After the inspection, verify the contents of the shipment. The kit
contains:
Differential probe (with high voltage input leads, CT3683)
z
(2) Hook probes, black & red (1000 V for CT3681) (7000 V for
z
CT3683)
(4) AA batteries
