These timers require a start input. A gate and reset input are optional. Inputs are controlled by external pushbuttons. Reset occurs when the power is removed or
when the reset input is supplied. The gate signal can be used to interrupt (freeze) timer functions. Timer functions resume when the gate input is removed. B style
timers are not equipped for gate input.

1. Use the flat screwdriver to set the selectors. Since selectors do not
turn all the way around, both clockwise and counterclockwise rotation
may be necessary.
2. The jIndicator 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 jOperation 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
lTime Range Selector
1. The lTime 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 lTime Range Selector to set the decimal point indica-
tor and time increment indicator to its corresponding pair of settings.
3. Since these configurations 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.

1 minute to 999 minutes 999
0.1 hours to 99.9 hours 99.9 H
Step 3 Desired Operation Selection Remarks
Set the precise period of time desired by using the mTime Setting Digital Switch.
Use the mTime Setting Digital Switch to set the desired
period of time. It is important to remember that the setting
of the lTime Range Selector determines the units of time
measurement as well as the implied decimal point location.
It is important to remember that the lTime Range Selector not only selects the time range but also influences the interpretation of the Digital Time Display.
Changing the lTime Range Selector setting changes the units of time measurement (seconds, minutes, hours) as well as the decimal point location.
