III.The panel

HV Terminal: HV side for UST test. Grounded for GST test.

LV Signal: Connect the UST input of the C&DF unit using a fully shielded cable. For GST testing, connect the GST input using a fully shielded cable as well. Unshielded connections will introduce significant errors, particularly during GST testing. It is highly recommended to use a metal box to shield any exposed wires or clips, and to connect this metal box to the common terminal.

Common Terminal: Left open if using full shielded cable to connect the standard and C&DF unit. Otherwise, connect ground for UST test, connect HV for GST test.

The instrument should be charged when the range selection is abnormal or when the display appears dim. "BATTERY CHARGING" is displayed when Charging power supply is connected. "OK" is displayed when finished. The standard can not be operated while charging.

LCD Display: Shows C&DF standard value and other information.

Keys: Four keys ↑↓→ SS(start/stop). Press SS to turn on power supply. Press SS one second to turn off. ↑↓→to select. The standard will automatically shut off after 90 seconds of last operation. The selected range keeps effective even the power supply is turned off. Never operate keys and keep safe distance while testing.

Insulated Legs: Always use the legs for both UST and GST test
