Using Adjustment Function

When using the adjustment function, measurements are displayed and recorded after being adjusted according to the conditions set by the user.

 IMPORTANT
  • When you are carrying out adjustment settings and formulating equations please take care with the settings and take personal responsibility for the process.
  • Note that the recorded data in the device will be erased when recording is resumed.
  1. Tap [Bluetooth] from the device info screen to open the Graph and Settings Menu, where you can check or change the settings via Bluetooth.

    If a recording is in progress, stop recording first before you proceed. (From the [Rec Settings] menu, tap [Stop] to stop the recording.)

  2. Tap [Other Settings].

  3. Under [Adjustment], tap the channel to which you wish to make adjustments.

    If you wish to make new adjustments on an already adjusted channel, it is recommended to tap [Initialize] to reset the settings first. (Initialized setting: y=1x+0)

  4. Select the adjustment method (1 Point Adjustment or 2 Point Adjustment), make adjustment entries, and then tap [Apply]. (Refer to Adjustment Entries and Guidelines)

  5. Start recording from the [Rec Settings] menu.

    The adjustment equation can also be found in the [Settings Table].

Adjustment Entries and Guidelines

The adjustment equation y=ax+b is determined by the adjustment entries. (x: Measurement Value, y: Post-adjusted Value)
An equation with a slope (a) and/or an intercept (b) exceeding the following ranges cannot be set.

  Temperature, Humidity
Slope (a) Range 0<a≦2
Significant Digits 3 decimal places
Intercept (b) Range within ±30 °C
within ±30 %
Significant Digits same as that of the data logger's measurement resolution

There are two possible methods of adjustment:
1 point Adjustment (Use when measuring in a range of ±20 °C)
2 point Adjustment (Use when measuring in a wide range).

 IMPORTANT
  • The difference between the values entered for "Before" and "After" must be ±5 °C or less. (Entries for temperature and humidity can be made in units of 0.1.)
  • Making adjustment settings will not guarantee the improvement of measurement accuracy for the whole measurement range.
  • By making new adjustment settings to an already adjusted device without first clicking the Initialize button, the new adjustment equation will be used to further adjust the previously adjusted result. Please be careful that in this case, the difference between the actual measurement (original value) and the post-adjusted value will be bigger than it should be.
    EX: When changing 0 to 0.1 (+0.1) in the first adjustment and 0 to 0.2 (+0.2) in the second adjustment, the difference will be 0.3 (0.1+0.2).
  • For 2 point Adjustment, it is important to make sure the points are not too close to each other. The probability of measurement errors will increase in other ranges outside of the two points. It is recommended to make the space between the two points 20 % or more of the measurement range for the Remote Unit.
  • When carrying out adjustment to the slope, adjustments will become larger in areas outside of the 2 points which were entered.

1 Point Adjustment

Use this to adjust all measurements with the same offset. (The whole graph will be adjusted up or down, keeping the same slope.)
This adjustment method changes only the intercept (b) where the slope (a) is considered to be the value of "one".

For example, the Remote Unit is measuring 10.2 °C, but the standard says the actual measurement should be 10 °C

Enter 10.2 in the "Before" box and 10 in the "After" box.
The conversion equation will be y=x−0.2 and for all measurements an adjustment to the offset of −0.2 will be made.

2 Point Adjustment

Use this to adjust measurements in a wide range or when adjustment cannot be carried out using only one point. The slope will change.
The adjustment equation will be calculated from two points: the slope (a) and the intercept (b).

For example, the data logger is measuring 0.2 °C and 9.6 °C, but the standard says the actual measurements should be 0 °C and 10 °C.

Enter 0.2 and 9.6 in the "Before" boxes and 0 and 10 in the "After" boxes.
In this case the slope (a) is (10−0)/(9.6−0.2) = 1.06.
The conversion equation is y=1.06x−0.213 with the intercept being −0.213.
