TM AC/DC Current Probe 925 Power/ Range Switch AC/DC Switch Low Battery Indicator Zero Adjustment OPERATOR’S MANUAL
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.
Measuring AC Current 1. Connect the Probe to the input terminals on the DMM. 2. Turn on the DMM and put the DMM in the DC millivolts measurement range. 3. Toggle AC/DC switch to select AC and turn on the Probe. Set the Probe on the 400A or 1000A measurement range. 4. Clamp the Probe around the conductor. 5. Read the Display Measuring DC Current 1. Connect the Probe to the input terminals on the DMM. 2. Turn on the DMM and put the DMM in the DC millivolts measurement range. 3.
SAFETY PRECAUTIONS —Read All Instructions Before Using The Probe— Never use the Probe on circuits with voltages higher than 600V rms. Keep your fingers behind the hand guard. Be extremely cautious when clamping around uninsulated conductors or bus bars. Accidental contact with the conductor could result in electric shock. Never use a Probe whose insulating protection has been impaired. Always wear eye protection when testing vehicles. Be extra careful near batteries and moving parts.
