Continuous measurement with pass/fail judgments

Generating pass/fail judgments for a succession of measured values and displaying them on a graph
Ideal for measurement applications in which there are a large number of measurement locations, for example insulation resistance measurement and maintenance of solar power installations.

Judgments for a succession of measured values sent using Bluetooth communications can be generated and displayed as a graph.

Features

Generating correct judgments even when there are numerous measurement locations

You can continuously measure numerous measurement locations, for example when measuring insulation resistance values at a distribution panel; record measured values; and review the pass/fail judgment results.

Make measurements with an instrument.
Press the instrument’s hold button to send the measured value via Bluetooth^® communications.
The measured value will be recorded, and the judgment result will be displayed on a graph.
Release the hold on the instrument and measure the next measurement location.

There’s no need to worry if you miss a measurement.

Simply tap and hold the bar graph to reenter a measurement.

Tap and hold the graph where you wish to remeasure or delete a measurement.

Setting pass/fail judgment conditions

Example setting 1 Fixed value: 50; judgment condition: “>” (greater than)
Example setting 2 Fixed value: 50; judgment condition “≤” (less than or equal to)
Example setting 3 Fixed value: 50; “±” added; judgment condition: “≤” (less than or equal to)
Setting example 4 Following the instrument’s measurement conditions	Generating judgments using comparator values set on the Insulation Tester IR4052-50/IR4054/IR4055 or Bypass Diode Tester FT4310.

Operation

Comparator function operating manual

Specifications

Number of simultaneous instrument connections	8
Pass/fail judgment	Measurement channels 1 channel Start method: Tap the [Start measurement] button. Judgment timing: Pass/fail judgments are generated and saved for the measured value when the instrument’s [Hold] button is pressed. Fail judgment criteria No judgment: Only measured values are saved. Follow instrument judgment: Judgments are made using the comparator values set on a compatible instrument (Insulation Tester IR4052-50/IR4054/IR4055 or FT4310). Judgment using fixed values: Judgments are made using a reference value and conditions (greater than, greater than or equal to, less than or equal to, less than). Judgment using measured data average values: The average of all measured values is used as the reference value.
Bar graph display	Green: Pass Red: Fail
