70 3.10 About Setting Contents 3.10.10 Hold Setting During measurement, the measured frequency value can be retained by the Hold function until the frequency of the next cycle has been determined. Also, if the value is not retained and the next value cannot be determined within a specified period, one half of the last measured value can be displayed. Setting Item: [Hold] Selections Description On Retains the measured value until the next frequency value is determined.
71 3.10 About Setting Contents Example: Measuring frequency dropping to 0 Hz, and then increasing Actual Phenomena Frequency drops from a certain cycle to 0 Hz, and then increases from that point. Hold: On The previous value is retained until the 0-Hz event. [Hz] 200 Hold: 10-ms Off At frequencies below 100 Hz, the displayed value is successively halved to 0 Hz. However, until the frequency reaches 100 Hz again, the halved signal is now added.

Move the cursor to [Sensitivity] to set the sensor sensitivity. Enter a multiplier value that will produce a settable value (0.1 to 10) when multiplied by the actual sensitivity of the sensor.
75 3.10 About Setting Contents 3.10.15 Probe Attenuation Selection Probe attenuation can be selected when measuring using a connection cable, differential probe or attenuating probe. (Only for voltage measurement) By matching the input channel probe setting to the attenuation ratio of a probe connected to an analog input module, the voltage axis range is automatically converted for direct reading of numerical values. Each channel should be set to match the attenuation ratio of its input probe.
76 3.10 About Setting Contents 3.10.17 Executing Zero Adjustment The input module can apply an internal offset to set the reference potential of the instrument to zero volts. Adjustment applies to the currently selected range. Before executing zero adjustment • Turn power on and wait 30 minutes to allow the internal temperature of the input module to stabilize. (Some input modules may require one hour warmup.) • Zero adjustment cannot be performed while measuring.
77 3.10 About Setting Contents Offset cancellation cannot be executed in the following cases: • When measuring other than voltage or current • When the input voltage is more than ±10 divisions from zero About input voltage during offset cancellation The maximum input voltage and maximum rated voltage to ground are unaffected by offset cancellation of an input voltage to zero volts. Therefore, careful attention is necessary during measurement.
78 3.10 About Setting Contents 3.10.19 Executing Auto-Balance Auto-balance sets the reference output level of a transducer to the specified zero position. It is applicable only to a strain module. Before executing auto-balance • Turn power on and wait 1 hour to allow the internal temperature of the input module to stabilize. • With the sensor connected to the input module, execute auto-balance under stable input conditions. • Auto-balance cannot execute during measurement.
