1. Introduction
This manual provides detailed instructions for the safe and effective use of the GOLDCHAMP GC-36D Digital Capacitance Meter. This portable device is designed for precise digital measurement of capacitance, suitable for identifying unknown capacitance values and testing capacitors in cables, switches, and PCB circuits. Please read this manual thoroughly before operation.
2. Safety Information
Always observe basic safety precautions when using electrical testing equipment to reduce the risk of fire, electric shock, or personal injury. Keep the device dry and clean. Do not attempt to measure live circuits or capacitors that are not fully discharged. Ensure the battery compartment is securely closed during operation.

- LCD Display: Shows measurement readings and indicators.
- Data-Hold Button: Freezes the current reading on the display.
- Backlight Button: Activates the display backlight for improved visibility in low-light conditions.
- Function Switch: Used to select the desired capacitance measurement range or turn the device off.
- ZERO Adjustment Knob: Used to zero out residual capacitance before measurement.
- Cx+, Cx- Input Jacks: Connectors for the test leads.
4. Setup
4.1 Battery Installation
The GOLDCHAMP GC-36D requires one 9V (6F22) battery for operation. To install or replace the battery:
- Ensure the device is turned off.
- Locate the battery compartment on the back of the meter.
- Open the battery cover.
- Insert a new 9V battery, observing the correct polarity (+/-).
- Close the battery cover securely.

4.2 Connecting Test Leads
Connect the red test lead to the Cx+ input jack and the black test lead to the Cx- input jack. Ensure a firm connection for accurate readings.
5. Operating Instructions
5.1 Power On/Off
Rotate the Function Switch from the "OFF" position to any desired measurement range to power on the device. To power off, rotate the Function Switch back to the "OFF" position.
5.2 Zero Adjustment
Before measuring, especially for small capacitance values, it is recommended to zero the meter. With the test leads disconnected from any component, select the desired range and rotate the ZERO adjustment knob until the display reads "000" or as close to zero as possible.
5.3 Selecting Measurement Range
The Function Switch allows selection of various capacitance ranges. Choose a range that is appropriate for the capacitor being measured. If the capacitance value is unknown, start with a higher range and decrease it until a stable and accurate reading is obtained.

Available ranges include:
- 200pF
- 2000pF
- 20nF
- 200nF
- 2uF
- 20uF
- 200uF
- 2000uF
- 20mF
5.4 Performing a Measurement
- Ensure the capacitor to be measured is fully discharged before connecting it to the meter.
- Connect the test leads to the capacitor terminals.
- Read the capacitance value displayed on the LCD.
5.5 Data Hold Function
Press the "HOLD" button to freeze the current reading on the LCD. Press it again to release the hold and resume live measurements.
5.6 Backlight Function
Press the "Backlight" button to illuminate the LCD display. This is useful in dimly lit environments. Press it again to turn off the backlight.

6. Maintenance
6.1 Cleaning
Wipe the meter with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the device.
6.2 Battery Replacement
When the battery indicator appears on the display, replace the 9V battery as described in Section 4.1. Remove the battery if the meter will not be used for an extended period to prevent leakage.
6.3 Storage
Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures. Keep it out of reach of children.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display or dim display | Low or dead battery | Replace the 9V battery. |
| Inaccurate readings | Incorrect range selected, un-zeroed meter, or faulty capacitor | Select appropriate range, perform zero adjustment, ensure capacitor is discharged and functional. |
| "OL" or Overload displayed | Capacitance value exceeds selected range | Select a higher measurement range. |
