Introduction

The Probe is a clamp-on AC/DC current probe for use with common digital
multimeters and labscopes. It has been designed and tested according to IEC
Publication 1010-2-032 (1994, 12) (Overvoltage Category III), Safety Requirements
for Hand-help Current Clamps for Electrical Measurement and Test, the EMC
Directive (EN 50081-1 and EN 50082-1). Designed to Protection Class II, Double
or reinforced insulation requirements of UL 3111, CAN/CSA C22.2 No. 1010.1­92, ISA-DC82, and IEC 1010-2-032.

Compatibility

The Probe is compatible with any 4000 count millivolt measuring device that has
the following features:

• Range and resolution capable of displaying millivolts with a 1 millivolt resolution
for the 400 Amp range, and a resolution of 0.1 Millivolt for the 1000 Amp
range.

• Accepts standard safety-shrouded plugs or a banana plug.

• Input impedance of greater than or equal to 10MΩ
