IV.Operation
1.Please study the instruction carefully and check if the connection is corret before power on.
2.The parameters can be set by the thumb switches and press keys.
SET: set and confirm key
RST: parameter selecting key
3.Operating process
◎Thumb switch setting,4-digit (FM4) or 5-digit (FM8) LED display,
◎Dimension(mm)：48H*96W、48H*48W,
◎4 alarm modes(U-U),(U-d),(d-U),(d-d) selectable,
◎With return difference setting,improve the stability of instruments and systems,
◎Multi purpose use: it can be used as frequency meter, line speed meter and tachometer
through software selection,
◎High measurement accuracy, fixed or floating decimal point display can be selected.
Relay 2 working mode
Relay 2 working mode,

1、The input wire should not be too long. We suggest use the shielded wire to improve the anti-interference capacity. The instrument
should not use in the environment of high humidity (>90RH%) or high acidity.
2、Means overload range“UUUU”.
3、If the instrument is for display only, we suggest to set the measuring range（RAN）as float decimal point ( 99.9.9.9 ),refresh time display
set as 0（auto refresh）
If the instrument is for alarm output, it should be set as fixed decimal point,and select the two relay as NO or NC.
4、Malfunction handling：
A：displaying not stable, relay malfunction.
*Use the shielded wire, let the input signal under the situation without high interference.
*Set the decimal point correctly（RAN Manu）.
*Use the pure power supply.
*Adjust the hysteresis corretly.
B：There is signal input, but the instrument displays 0.
*Check if the wire connection is corr ect.
*Check if the situation of diagrams is correct
*Check if the refresh time is correet.
