k Operation
Mode Selector
1. Use the fl at screwdriver to set the selectors. Since selectors do not
turn all the way around, both clockwise and counterclockwise rotation
may be necessary.
2. The j Indicator Mode Selector determines whether the Digital
Time Display shows the time elapsed or time remaining. The k
Operation Mode Selector determines the desired operation mode.
Decide which display and mode is desired, then use these two selec-
tors jk to set the operation mode.
3. The j Operation Mode Selector has two blank modes which are
not intended for use. Always have this selector set to A, B, C, or D.

Step 2 Desired Operation Selection Remarks
Select a time range
that contains the
desired period of time.
Base Time Ranges
l Time Range Selector
1. The
l Time Range Selector controls both the decimal point indica-
tor (9.99, 99.9, 999) and the time increment indicators S (seconds), M
(minutes), and H (hours).
2. Chose which base time range contains the targeted timer setting.
Then use the l Time Range Selector to set the decimal point indica-
tor and time increment indicator to its corresponding pair of settings.
3. Since these confi gurations offer a complete range of settings from
0.01 seconds to 99.9 hours, the setting of 9.99 for minutes and the
9.99 and 999 settings for hours are not listed and should not be used.

Step 3 Desired Operation Selection Remarks
Set the precise period of time desired by using the m Time Setting Digital Switch.
Use the m Time Setting Digital Switch to set the desired
period of time. It is important to remember that the setting
of the l Time Range Selector determines the units of time
measurement as well as the implied decimal point location.
It is important to remember that the l Time Range Selector not only selects the time range but also infl uences the interpretation of the Digital Time Display.
Changing the l Time Range Selector setting changes the units of time measurement (seconds, minutes, hours) as well as the decimal point location.
