Digital Gauges: Frequently Asked Questions

Question number FAQ-0087

Description of the preset measurement function for DG-825, DG-925, DG-525, and DG525H.

This function sets the display to a pre-configured value and performs measurements from that value. The maximum setting value is 69.99 (or 69.999 mm).

For example, when measuring the dimensions of a part that is approximately 50mm ± 10mm, if you set a reference point with a 50mm gauge block, preset it to 50.00, and then measure the part, the display will show a measurement of 40mm to 60mm.

Measurement method

<1> Switching preset functions

When the power is on, the display shows the normal measurement function.
The +/- direction switch cannot be selected in the preset measurement function. Please select the counting direction in the normal measurement function state.

Switching from the normal measurement function to the preset function is done by pressing and holding the MODE switch for approximately 2 seconds and then releasing it. A "P" mark will appear on the display.
At this time, a pre-set number will be displayed. (If not set, it will be 0.00)
Measurements can be taken using a combination of MAX/MIN/R measurement modes.

<2> How to return to normal measurement function

To return to normal measurement function, press and hold the reset switch for approximately 2 seconds, then release it. The "P" mark on the display will disappear and the value will return to 0.00.

<3> Switch operation during preset measurement

This demonstrates how to use the preset function.

RESET：

○ Press lightly and release.

The spindle position at the moment the switch is pressed and released is displayed, with a preset value.
Measurements can be taken in combination with MAX/MIN/R measurement modes. The initial values in this case are shown in the table below.

mode	Initial value (display value)
R	0.00
MAX/MIN	preset values

● Press and hold for approximately 2 seconds, then release.

The system will now return to normal measurement functions.

MODE：

○ Press lightly and release.

The measurement mode cycles through the following steps: Normal Measurement Mode → MAX Mode → MIN Mode → R Mode → Normal Mode. Select the desired measurement mode and begin the measurement. Pressing the RESET button will return the measurement to its initial value.

● Press and hold for approximately 2 seconds, then release.

The "P" mark will blink, and the display will change to one where you can input a preset value.

POWER：

The power will turn off. When you turn the power back on, it will return to the normal measurement function display.

<4> How to set preset values

1. Switch to preset settings display

Press and hold the MODE button for approximately 2 seconds, and the "P" mark will appear.
Continue pressing the MODE button until the "P" mark flashes, then release it.
The "mm" display disappears, the polarity indicator (+ or -) blinks, and the display switches to the preset settings.

2. Setting the values

Use the MODE switch to change the settings.

MODE：

○ Press lightly and release.

Select the polarity and numerical value. Pressing the button will move the blinking indicator from polarity (+/-) to numerical value. The blinking indicator will then show where you can enter the set value.

●Press and hold for approximately 2 seconds, then release.

The polarity and value of the blinking digit are determined, and the blinking then moves to the digit to the right.

(1) When the polarity (+/-) is flashing, each press of the MODE switch will alternate between displaying + and -. Press and hold the mode switch for about 2 seconds until the desired polarity is displayed, then release the switch when the flashing moves to the rightmost digit.

(2) When the numbers are flashing, each time you press the MODE switch, it will repeatedly display 1→2→3→4→5...0 (up to 6 for the most significant digit). Display the number you want to set and press the MODE switch for about 2 seconds until the next digit flashes.

(3) After setting the last digit, press and hold the MODE switch for about 2 seconds until only the "P" mark flashes. Press and hold it again or continue pressing until "mm" is displayed, then release the MODE switch to finish setting and save the setting value.
The display has returned to the preset function, so press the RESET button, confirm that the preset value is displayed, and start the measurement.

(4) If you want to cancel the settings midway
Press the RESET switch to return to the preset measurement function.

(5) The preset values are retained even when the POWER is turned off. However, performing a system reset will reset them to the initial value of 0.00 (or 0.000).
