(3) MODE Key: Selects a setting mode.
(4) SUB-MODE Key: Re-lights displays. (UP Key,DOWN Key or MODE Key also re-lights displays.)

Displays and Indicator
Input display: Indicates the input value.
Indication of -2000 or less: The minus (-) sign andinput value light alternately.
Indication of 10000 or more: The lower 4 digits flash.
Under range: -10% of input span or less:“” flashes on the Input display.
Over range: 110% of input span or more:“” flashes on the Input display.
Warm-up indication: The CH1 input type is displayed on
the Input display, CH2 input type is displayed on theSet value display for 3 sec after power is turned ON.
Set value display: Alarm 1 (A1), Alarm 2 (A2), Alarm 3(A3) values are indicated (follows the selection in“Display selection”.).
If the UP Key is pressed for 1 second during alarm value
indication, alarm values will be switched thus.
(A1A2

When power is turned ON, A1 value is indicated.
When alarm output is ON, the relevant CH1/CH2
indicator with the alarm ON flashes, and “” and thevalue selected in [Display selection] are alternatelyindicated on the Set value display. If the UP Key is

Auto-light function: Automatically measures and controls
brightness of the displays to conserve power.
Power failure countermeasure:The data is backed up in non-volatile IC memory.
Self diagnosis: The CPU is monitored by a watchdog timer,
and when an abnormal status is found on the CPU, theunit is switched to warm-up status turning all outputs OFF.
