BESANTEK 6. MEASUREMENT Before proceeding with measurement, read the safety notes. (1) AC Voltage measurement • Insert the BLACK test lead to COM and the RED one to the other terminal. • Set the function switch to ACV. • Connect the test leads to the object to be measured. - Page 15 BESANTEK (3) AC Current measurement • Set the function switch to ACA. • Press the jaw trigger to open the transfomer jaw and clamp onto one conductor only. • Read the display. (4) DC Current measurement • Set the function switch to DCA.
- Page 16 BESANTEK Diode measurement mode shares the same configuration with 4.000V manual voltage measurement mode. If the test circuit is open or the voltage drop between the two ports of the device (diode) under test are larger than 2V, the LCD panel will show "OL" ..
- Page 17 (7) Frequency measurement Switch to frequency measurement mode. Insert the BLACK test lead to COM and the RED one to the other terminal. Apply the test leads to the points across which the frequency is to be measured, and read the result directly from the display.

BESANTEK 7. MAINTENANCE Battery Replacement: When the low battery warning sign appears, replace with a new battery as follows: (1) Disconnect the test leads from the clamp meter and turn off the power. (2) Unscrew the battery cover and replace with a new Battery. - Page 19 CAT IV - Is for measurements performed at the source of the low voltage installation. CAT III - Is for measurements performed in the building installation. CAT II - Is for measurement performed on circuits directly connected to the low voltage Installation. CAT I - Is for measurements performed on circuits not directly Connected to Mains.
