Use extreme caution when clamping around bare conductors or bus bars INTERNATIONAL ELECTRICAL SYMBOLS o This symbol signifies that the current probe is protected by double or reinforced insulation Use only factory specified replacement parts when servicing the instrument A This symbol signifies CAUTION and requests that the user refer to the user manual before using the instrument This is a type A current sensor This symbol signifies that application around and removal from HAZARDOUS LIVE conductors is permitted DEFINITION OF MEASUREMENT CATEGORIES Cat l For measurements on circuits not directly connected to the AC supply wall outlet such as protected secondaries signal level and limited energy circuits Cat Il For measurements performed on circuits directly connected to the electrical distribution system Examples are measurements on household appliances or portable tools Cat Ill For measurements performed in the building installation at the distribution level such as on hardwired equipment in fixed installation and circuit breakers Cat IV For measurements performed at the primary electrical supply lt 1000V such as on primary overcurrent protection devices ripple control units or meters RECEIVING YOUR SHIPMENT Upon receiving your shipment make sure that the contents are consistent with the packing list Notify your distributor of any missing items If the equipment appears to be damaged file a claim immediate
3. 0 mA 2500 mA 1250 mA Select the 10 A range on your DMM or instrument Use the switch on the inside handle to select the 1000 5 range Clamp the probe around the conductor and work down until the appropriate range and resolution in reached Take the reading on the meter and multiply it by the ratio selected to obtain the measured current e g 500 mA reading 500 x 200 100 000 mA or 100 A with the 1000 5 ratio e For best accuracy avoid if possible the proximity of other conductors which may create noise Tips for Making Precise Measurements e When using a current probe with a meter it is important to select the range that provides the best resolution Failure to do this may result in measurement errors e Make sure that probe jaw mating surfaces are free of dust and contamination Contaminants cause air gaps between the jaws increasing the phase shift between primary and secondary It is very critical for power measurement MAINTENANCE Warning e For maintenance use only original replacement parts e To avoid electrical shock do not attempt to perform any servicing unless you are qualified to do so e To avoid electrical shock and or damage to the instrument do not get water or other foreign agents into the probe Cleaning To ensure optimum performance it is important to keep the probe jaw mating surfaces clean at all times Failure to do so may result in error in readings To clean the probe jaws use very fine sand paper fi
4. AC Current Probe Model SR634 User Manual DESCRIPTION The SR634 Catalog 2113 48 is designed for use in industrial environments The ergonomic design allows it to easily attach to cables or small bus bars The circular jaws guarantee a very good accuracy and low phase shift The probe has a measurement range up to 1000 Arms continuous and is compatible with any AC Ammeter multimeter or other current measurement instrument with an input impedance lower than 0 6Q To achieve the stated accuracy use the SR634 with an ammeter having an accuracy of 0 75 or better WARNING These safety warnings are provided to ensure the safety of personnel and proper operation of the instrument Read the instruction manual completely and follow all the safety information before attempting to use or service this instrument Use caution on any circuit Potentially high voltages and currents may be present and may pose a shock hazard Read the Safety Specifications section prior to using the current probe Never exceed the maximum voltage ratings given Safety is the responsibility of the operator ALWAYS connect the current probe to the display device before clamping the probe onto the sample being tested ALWAYS inspect the instrument probe probe cable and output terminals prior to use Replace any defective parts immediately NEVER use the current probe on electrical conductors rated above 600V in overvoltage category Ill CAT III
