Js-visg-m-s Manual -

JS-VISG-M-S is a handheld, portable signal generator used primarily for testing and calibrating industrial equipment like PLCs and transmitters. It can output both voltage ( ) and current ( ) signals. Key Technical Specifications Voltage Output: (adjustable, precision Current Output: (adjustable, precision Power Supply: external power or a lithium battery. Can be charged via microUSB ( 4-digit digital display showing two decimal places. Common Operations & Programming To access the configuration menu on most versions (like the Enter Menu: Press and hold the encoder knob for until the screen displays "F001". Unlock Settings:

Memory Function: The device can save a specific output value as a default, which it will automatically output upon being powered on. Programming and Configuration (Key Parameters) The user manual defines specific parameter codes ( F001cap F 001 F002cap F 002 , etc.) to customize the unit's behavior: Description F001 Adjustment Type Sets the knob to "Coarse" (0) or "Fine" (1) adjustment. F002 Output Range Configures ranges such as F003 Display Mode Switches display between actual signal value (0) or scale (1). Operational Instructions js-visg-m-s manual

1. Power On: Apply power to the unit.
2. Horizontal Alignment:

   Splicing instructions:

   • Use a PM fusion splicer in “auto-align” mode.
   • Target extinction ratio: ≥25 dB after splicing.
   • The manual includes a power-through versus rotation angle graph: if you rotate the input fiber while launching polarized light, the output power should dip by >25 dB at 90° offset.
