OPERATION: · Remove the protective cap. · Turn the meter on with the ON/OFF switch located on the top of the meter. [. . . ] · In case of erroneous readings even after an accurate conditioning and calibration, the reference junction might be contaminated or clogged. · Pull out 2 mm (1/8'') of the cloth junction to renew the electrode reference (it is recommended to cut the cloth leaving always at least 2 mm 1/8'' over the reference compartment) and repeat the maintenance and conditioning proce-
dure. The cloth junction can be pulled out approximately 20 times. After that, the electrode can be replaced (see the Electrode Replacement section).

When the batteries are too low, the meter automatically switches itself off. To replace the batteries, slide off the battery compartment cover and replace all four 1. 5V batteries while paying attention to their polarity.
Batteries should only be replaced in a nonhazardous area using the battery type specified in this instruction manual.
