- Page 3 Signal Input Connections The input terminals of IN-1, IN-2, RST and HOLD are internally connected with pull-up resistance, so when the terminals are not wired (suspended), the input on IN is a high level state. When the RST and HOLD terminals are not used and are suspended, the input logic of RST and HOLD should be reversed, that is, the parameter value of RH-N is ON (see "7.

The panel buttons are used to set the parameters They have a second function, in regular mode. The key is used as the MAX / MIN (maximum / minimum) key to switch between the current values, the maximum value and the minimum value.

Page 11: Functional Description
Functional description The instrument has 18 measuring functions, F01 to F18, and is set in the parameter FUNC. The graphical and literal descriptions of pulse signals in the following paragraphs, if not specified, refer to the case of input uncorrelated closure (IN-N = OFF, RH-N = OFF). F01, F02, F03, F04 F01 - Independent input and subtraction counter F02 - Instruction input plus and minus counter... - Page 12 The counter functions F01, F02, F03 and F04 are measured by using the following formulas: measurement value = count *A_B+C A, B: ratio factor. Set the ratio factor to convert the count value into the unit of measurement. C: the initial value of the counter, so that the measurement starts with the desired value. For example, the encoder with output pulse 1000p/r is used in the measurement of sheet metal length in the following figure.

If necessary, it can be installed in • external lines. Do not install the instrument near devices that can generate strong high frequency waves or • surges (such as high-power converters, motors, welding machines, transformers, etc.). Signal lines should be separately wired away from power lines with high voltage or high current, and not parallel to or within the same cable.
- Page 18 Matters needing attention: Please read the instructions carefully before using the meter. • The instrument should be used in a standard environment (such as temperature, humidity, etc.). • Please do not close the meter, and keep enough space for heat dissipation. Please do not disassemble the meter.
