Apply tension to the belt following the manufacturer’s recommended method until the
required reading is reached, using either display or LED/sound methods. Then lock off the
tension adjustment.
To ensure that the tension applied to the belt is correctly distributed, remove the Measuring
Head and turn the crankshaft until the engine is in the position that would be appropriate for
valve timing checking/belt replacement. This is normally TDC on the compression stroke on
number one cylinder. Refit the 5846 and re-test.
Note
: If at any time whilst tightening the clamp, the coloured LED goes off, the beeper
sounds continuously and the message
INF1
appears on the display,
stop tightening
the clamp immediately
or the measuring head will be damaged. If this happens, a new
measuring head will need to be obtained and calibrated to the tester before using it again or
the instrument must be returned to the manufacturer for head replacement.
Precautions
• To secure accurate results it is essential that the operating procedure is followed carefully.
• The belt tension between the measuring points will vary as the engine is rotated
due to differing internal loads on the crankshaft, camshaft, etc. For this reason, it is
recommended that at least two measurements are taken with the crankshaft turned to
two different positions.
• Do not forget to remove the measuring head before rotating the crankshaft. Always
zero the instrument every ten minutes if the instrument is being used for a long time.
• Do not forget that the zeroing must be done with the measuring head removed from
the belt, and the clamp fully unscrewed.
• The instrument must only be used with the measuring head with which it has been
calibrated. The measuring head can not be exchanged, swapped or replaced unless
the machine is fully re-calibrated.
• If the instrument is used with a different measuring head, it must be re-calibrated
before using.
• To avoid potential irreparable damage, never clamp the measuring head onto a belt
unless the head is plugged in and the instrument is switched on. The instrument warns
of a head overload condition, but only if the head is plugged in and the unit switched on.
• Never clamp the measuring head onto an inflexible object such as a metal or wooden bar.
• Never drop the instrument or subject it to sharp impacts.
• Never allow the instrument or measuring head to hang by the connecting cable.
