Installation Specifications

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.

Environmental Specification
RoHS directive compliance

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 -200.0 or less (ranges with decimal point):
The minus (-) sign and input value light alternately.
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 onthe Input display, CH2 input type is displayed on the Set
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
A3A1).
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 alternately
indicated 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 will bedisplayed.
