signals.
6 input ranges available: 4 to 20 mA/0 to 20 mA, 1 to 5 VDC/
0 to 5 VDC, 5 VDC, 10 VDC.
• 5 KHz max. input-pulse frequency range.
• Scaling in a wide range of engineering units.
• Programmable output operation action, decimal point
position setting, teaching function for input range, leading
zero suppression, average processing.
• Advanced and compact design
• Very compact 1/32 DIN housing: 48 (W) x 24 (H) x 83 (D).
• 5-digit display with programmable display color in red or
green.
• Good visibility: High contrast backlit LCD display.
• High protection against water and dust: NEMA4X/IP66 front
panel.
• Selectable outputs: 2 relay outputs, 3 transistor outputs,
RS-485, and combinations of these.
• High accuracy: 0.1% full scale.
• Easy to configure through the front panel or via RS-485.

Approx. 100 g Note: A control power supply capacity greater than the rated capacity is required when the Digital Panel Meter is turned ON. Do not forget to take this into consideration when using several Digital Panel Meters. When power is supplied, all indicators will light and outputs will be OFF. - Page 3 “ ” is displayed automatically with a negative input signal. Zero display Leading zeros are not displayed.

An upper limit (H set value) and lower limit (L set value) can be set independently. The output is turned ON when the measured value is greater than upper-limit set value or less than the lower-limit set value. Only transistor outputs have a PASS output which is output when both OUT1 and OUT2 are OFF. - Page 10 5. Mode Key Used to allow the Main display to indicate parameters sequentially. 6. Shift Key Used to enable that set value to be changed. When changing a set value, this key is used to move along the digits. 7. Up/Zero Key Used to change a set value.

Page 14: Operating Procedures
Operating Procedures ■ Initial Settings Power ON Press the Level Key @ for 3 s min. to move to the initial setting level. Select the input type and specify the analog input range or pulse frequency input range. Set the scaling values and specify output operating action as required. - Page 15 ■ Levels “Level” refers to a grouping of parameters. The following table lists the operations that are possible in each of the levels, and how to move between levels. There are some parameters that are not displayed for certain models.
- Page 16 ■ Parameters Note: 1. Some parameters are not displayed for certain models. 2. The K3GN will stop measurement if the level is changed to the initial setting level, the advanced function setting level, the communications setting level, or the calibration level.

Page 20: Additional Information
Additional Information ■ Application as a Process Meter The initial settings required when using the K3GN a process meter are explained below using the following example. Setting Example Initial Setting Procedure Inputs in the range 1 to 5 V are scaled to the range 0 to 100.0 kg and 1. - Page 21 Set parameter in-t to pulse. 3. Set the pulse frequency to 30 Hz. The input pulse frequency for the application is approximately 2 Hz and so can be assumed not to exceed 30 Hz. Set parameter p-fre to 30. 4. Set the scaling values.
