Page 3: Safety Warnings
1. Safety Warnings This instruction manual contains warnings and safety rules which must be observed by the user to ensure safe operation of the instrument and retain it in safe condition. Therefore, read these operating instructions thoroughly and completely before using the instrument. - Page 4 8. Do not make measurements in an explosive atmosphere (i.e. in the presence of flammable gasses or fumes, vapor or dust). 9. Calibration and repair of any instrument should only be performed by qualified and trained service technicians. Do not attempt calibration or service unless another person capable of rendering first aid and resuscitation is present.

2. Features DSA-2417 offers True RMS measurement capability. Designed for measurements of AC leakage and AC current with five ranges from 200mA to 500A. AC 200mA range provides a high resolution of 0.1mA. Least affected by external magnetic field. Provides dual frequency responses of fundamental 50/60 Hz only or up to 1 kHz. -

5. PREPARATIONS FOR TESTS WARNING Always inspect your instrument and accessories for any sign of damage or abnormality before every use. If any abnormal conditions exist (eg. cracked cases, display not reading, etc.), do not attempt to conduct any tests. 5-1 Battery Check To check the battery voltage set the Power/Range Selector Switch to OFF position. -

6. OPERATING INSTRUCTIONS 6-1 Current Measurements WARNING • Do not make measurements where the potential is greater than 600V AC. This may cause shock hazard and damage to the instrument or equipment under test. • The Transformer Jaws are made of metal and their tips are not insulated. - Page 12 NOTE • When making current measurements, keep the Transformer Jaws fully closed. Otherwise, accurate measurements cannot be taken. Maximum conductor size is 40mm in diameter. • When measuring larger current, the Transformer Jaws may buzz. This is not a fault and does not affect the accuracy either. ⑴Set the Range Switch to the desired “A”or “mA”position.

Page 13: Frequency Selector Switch
NOTE • For more accurate measurements, place the conductor at the center of the closed jaws. • When measuring current on a line or a grounded wire, clamp onto one conductor only. ⑷ When measuring out of balance leakage current, clamp onto all conductors except a grounded wire as shown in Fig. - Page 14 NOTE • DSA-2417 has a very good frequency response due to the electrical property of the transformer jaws used for the instruments. Therefore, it measures AC current of not only 50 Hz or 60 Hz fundamental wave form but also of higher frequencies and harmonics superimposed on the fundamental frequency when present in the circuit under test.

7. BATTERY REPLACEMENT 7-1 When to replace the battery ⑴When “B”symbol is displayed on the digital display. ⑵ When the digital display does not read with the Power/Range Selector Switch set to ON position. 7-2 Battery replacement ⑴Set the Power /Range Selector Switch to OFF position. ⑵Unscrew and remove the battery compartment cover as shown in Fig. - Page 17 Be sure to include your name and address, as well the name of the distributor, with a copy of your invoice from whom the unit was purchased, clearly identifying the model number and date of purchase.
