*3: If this is lit up, refer to “Error Display and Recovery Procedures” of the “Operation Manual
(Detailed Version)”.
*4: Turning the power off when the battery voltage is low deletes the current time and logging data.
(Set values for logging ID, logging mode, logging start time, detailed data logging cycle and
logging items are not deleted due to being stored in non-volatile memory.) Replace the
battery if BAT. LED lights up.
