An lead with a 3-pole 3.5 mm jack on one end (plugs into
“RS 232 OUT”) and a 9-pin female D-Subminiature connector on the other end (plugs into the PC’s serial port) will be required to link the instrument with a PC. The output is a 16-digit data stream that may be utilized by accessory item# 4237 (See the “Optional Accessories” section) or by user specific applications.
ALL OPERATION DIFFICULTIES
If this meter does not function properly for any reason, replace the battery with a new, high-quality battery (see the
“Battery Replacement” section). Low battery power can occasionally cause an number of “apparent” operational difficulties. Replacing the battery with a new fresh battery will solve most difficulties.
BATTERY REPLACEMENT
An erratic display, faint display, no display, or a battery icon appearing on the display are all indicators that the battery needs replacement. Remove the battery compartment screws. Lift out the battery compartment. Remove the exhausted battery and replace it with a new 9 volt alkaline battery. Replace the battery compartment and tighten the screws securely.
