Settings
Function keys
(1) UP Key: Increases a numerical value.
(2) DOWN Key: Decreases a numerical value.
(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.
(A1A2A3A1).
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 ispressed together with the DOWN Key in the above
status, the alarm output currently being turned ON willbe displayed.
(E.g.) If CH1 Alarm 1 and CH2 Alarm 3 outputs are ON,“” and “” are displayed in order.
Power indicator (green): Lit when power is turned ON.
CH1 indicator (yellow): Lit when CH1 is selected in[Display selection].
CH2 indicator (yellow): Lit when CH2 is selected in[Display selection].

Circuit Configuration & Terminal Arrangement

Attached Functions
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.
