Page 3: Safety Precautions
1. Safety Precautions Electricity can cause severe injuries, even with low voltage or current. Therefore, it is extremely important that you read the following Information before using your Electrical Network Analyzer. 1.1 This Instrument must only be used and operated by a competent trained person and in strict accordance with the instructions. - Page 4 1.5 Before use, always inspect the tester and test leads for any sign of abnormal condition or damage. If any abnormal conditions exist (broken test leads, cracked case, display faulty, etc...) do not attempt to take any measurement or use the tester.

Page 9: What Does The Tester Measures
BESANTEK 7. What does the Loop/ Psc / Load Tester measures? VL-N N PS� VL-N@OA voltage generator (supply transf o rmer). Impedance of the line wire from the transf o rmer (including the internal impedance of the transformer) plus impedance of the earth path. -
Page 10: Functions
8. Functions The tester measures : ● Line - Earth loop impedance. ● Line - Neutral AC voltage at 16A. ● Prospective short circuit current L-N. (This is the current which will flow between Line and Neutral. A short circuit should be made between Line and Neutral). -
Page 11: Preparation For Measurement
9. Preparation for Measurement Before testing always check the followings : ● System voltage Your Electrical Network Analyzer is best intended to work with 230 V AC. However, if the voltage is lower than 230V, the test could still be done but accuracy of the PSC could deteriorate due to the fact that the current injected is lower than optimal. -

BESANTEK 10. Loop/ PSC / Load Testing Turn the instrument ON by pressing "ON / TEST" . T he LCD display will come to the first screen. LOOP/PSC/LOAD PRESS "TEST" Pressing "ON/ Test" will start the test. This testing procedure is automatic and controlled by the Microprocessor. -
Page 13: Battery Replacement
11. Battery Replacement ● The tester continuously monitors the battery voltage and in dictates when the battery needs to be replaced. ● The tester's batteries are situated under the tester. ● Disconnect the test leads from the instrument and remove the battery cover and the batteries. ●... -
Page 14: Cleaning And Storage
13. Cleaning & Storage Periodically, you should wipe the case with a damp cloth and detergent; do not use abrasives or solvents. If the meter is not used for long periods or longer than 60 days, remove the batteries and store them separately.
