2. Operation
a) Select the correc t bat ter y type and voltage w ith t he recessed range sw itch. Examples:
- move the r ange s elector to t he pos it ion labelled "1. 5V AA-C-D " if you w ish to t es t AA-, C- or D-batteries of 1.5V.
- select t he "9V"-position t o test r ectangular 9V-batteries.
- select t he "BU TTO N CELL 1.5V"-position to test mercur y, silver or alkaline button cells.
- select t he "LITHIUM 3V"-position f or lithium button cells.
- select t he "1.5V AA-C-D"-posit ion to t es t nickel cadmium batter ies of 1.25V and read the value on t he low es t of
t he thr ee s cales on the analogue display.
The value ind icated on the meter is the load cur rent drain placed on the battery dur ing the check.
CAUTION: Selecting the w rong range will yield inaccur ate result s. You may also damage the device in the pr oc ess .
b) P lace the r ed probe t ip (+) against the posit ive (+) battery t erminal and t he black probe t ip ( -) against t he negative ( -)
bat ter y terminal.
CAUTION : Mind the polarity indicat ions when t esting your batteries!
Select the correc t r ange (see above) . U s e the f ollow ing procedur e to t es t your batt eries:

- D o not push the brown sw itch w hen us ing the probe tips to test a but ton cell.
- D o not allow the r ed probe tip ( +) to contact the black probe t ip (-) when using t he 9V-contacts to test button cells.
c) R ead the analogue displ ay to deter mine the condition of the batt ery.
- U se the upper s cale ("R EGULAR" ) f or measuring regular z inc carbon and alkalin e batteries.
