TOTAL
“Total Counting Mode” in Counter and
Tachometer function
TMR
Light on when Timer function is executing
Key Operation
Increase and decrease SV or change parameter settings.
Left move 1 digit of the selected digit. The indicator of the selected digit will flash.
MODE
Save the set parameters or switch among functions.
LOCK
Prevent settings from being changed. Key-protected mode still works after the power is switched off. Press
LOCK to enter key-protected mode. In non-key-protected status, press LOCK to enter Lock 1. In Lock 1,
press LOCK again to enter Lock 2. Press
MODE
and
at the same time to disable key-protected mode.
(Lock 1
)
disables the functions of all keys.
(Lock 2) allows users to change SV and
functions of RESET remain. LOCK only functions in non-key-protected status.
RESET Clear and reset PV.
Modes: Operation Mode and Configuration Mode
Operation
When the power is on, the timer/counter/tachometer is in the operation mode. Press
to
change SV, or
to make change on a desired digit. The indicator of the selected digit will flash.
After the change is made, press
MODE
to save the setting. If SV or parameters are not changed, press
MODE
once to switch between SET1 and SET2.
Configuration
Press
MODE
in operation mode
for more than 3 seconds to enter configuration mode. Press
MODE
once to switch among parameters. To return to operation mode, press
MODE
for more than 3 seconds.
