General Tools and Instruments CT6235B - Manual (Page 7)

SETUP INSTRUCTIONS
INSTALL BATTERIES
To gain access to the battery compartment, slide its cover in the
back of the instrument (callout H of Fig. 2) down and away from
the unit. Then install four “AA” batteries in the correct orientation,
using the polarity marks on the inside of the compartment as a
guide. Don’t forget to install the batteries over the ribbon, which
makes it easier to remove them later. Replace the battery com-
partment cover, tucking the end of the ribbon under it.
OPERATING INSTRUCTIONS
SIMULATING SPEED MEASUREMENTS
Before using the CT6235B on actual equipment, General sug-
gests that you familiarize yourself with the way the instru-
ment measures, stores and recalls speeds by spinning the
tachometer’s shaft by hand. By simulating readings you can
expect to see in practice, you will safely gain expertise that
will save you time later.
To get started, make sure the black plastic sleeve (see
Fig. 1 (B) ) is installed on the tachometer’s shaft (callout C of
Fig. 2), with the slot of the sleeve over the shaft’s metal pin.
Cradle the tachometer in your right hand. Move the function
switch (callout E of Fig. 2) to either the “m/min” or “rpm”
position. Then press the Measurement button on the right
side of the instrument (callout D of Fig. 2) with your right
thumb. Note that this illuminates the display window. The dis-
play should show “0”, either with the letters “rpm” directly
below it or with the letters “m/min” below it to the left, de-
pending on the position of the function switch.
