Chapter 13 Specifications
263
13
(15)Self-Calibration Function
(16)Contact Improvement Function
(17)Faulty Measurement Detection
Operation Compensates for offset voltage and gain of measurement circuit
Setting AUTO/ MANUAL
Compensation timing AUTO : At power-on, after measured value, during TRIG standby (every 1 s)
MANUAL: During EXT I/O CAL signal input, when executing the calibration
command
Self-calibration time At power-on, when switching to auto and during manual execution: 400 ms
Auto: 5 ms (moving average)
Default setting AUTO
Operation A voltage is applied between the SENSE A and SENSE B terminals after TRIG
signal input, and a contact improvement current is allowed to flow for 0.2 ms.
Setting OFF/ ON (When LP is on, the contact improvement function is fixed to off.)
Default setting OFF
Applied voltage Max. 5 V
Contact improvement
current
Max. 10 mA (flowing to the measurement target)
Over Detection Function
Operation Indicates under- or over-range values in the following conditions:
• Measured value is outside of the measurement range
• Measured value is outside of the A/D converter input range
• Calculation result exceeded the number of display digits
Contact Check Function
Operation Checks the connections between SOURCE A and SENSE A, and between
SOURCE B and SENSE B terminals
Setting ON/ OFF (When using the MUX measurement terminal setting with the 2-wire
measurement method, fixed to off. When using the 100 M or greater range,
the setting is fixed to ON.)
Threshold 50 (reference value)
Default setting ON (When LP is off), OFF (When LP is on)
