5. Setup

5.1 Battery Installation

Both devices require batteries for operation. Locate the battery compartment on the back of each device. Insert the specified AAA batteries, ensuring correct polarity as indicated inside the compartment. Securely close the battery cover.

5.2 Multimeter HT118A Initial Setup

After battery installation, the HT118A is generally ready for use. Connect the test leads to the appropriate input jacks based on the measurement type. The LED Lightning Jacks will assist in correct placement.

5.3 Paint Thickness Gauge KOTCO2 Calibration

For accurate measurements, it is recommended to calibrate the KOTCO2 gauge before first use and periodically thereafter. The device is factory-calibrated, but user calibration modes are available:

1. Zero Point Calibration: Place the probe firmly and perpendicularly on the bare ferrous or non-ferrous calibration plate. Press the "ZERO" button to set the zero point.
2. Multi-Points Calibration: Use the provided calibration films of known thickness (e.g., 50µm, 100µm) on the calibration plates. Follow the on-screen instructions or refer to the detailed calibration section in the full manual for precise steps to adjust the gauge for optimal accuracy across the measurement range.

Ensure the calibration plates and films are clean and free from dust or debris during calibration.

6. Operating Instructions

6.1 KAIWEETS Digital Multimeter HT118A Operation

1. Power On/Off: Rotate the central dial from "OFF" to the desired measurement function to power on. Rotate back to "OFF" to power off.
2. Function Selection: Use the central dial to select the primary measurement type (e.g., V for voltage, A for current, Ω for resistance). Press the "FUNC" button to cycle through sub-functions within a category (e.g., AC/DC voltage, diode/continuity).
3. Connecting Test Leads: Insert the black test lead into the "COM" jack. Insert the red test lead into the appropriate jack for your measurement (e.g., VΩmA for voltage/resistance/small current, 10A for large current). The LED Lightning Jacks will illuminate to guide you.
4. Making Measurements:
   • Voltage: Select V~ (AC) or V- (DC). Connect leads in parallel with the circuit.
   • Current: Select A~ (AC) or A- (DC). Connect leads in series with the circuit. Ensure the circuit is de-energized before connecting.
   • Resistance: Select Ω. Connect leads across the component when it is de-energized.
   • Continuity: Select the continuity function (usually indicated by a speaker icon). A beep indicates continuity.
   • Temperature: Connect the temperature probe (if included) to the appropriate jacks and select the temperature function.
5. HOLD Function: Press the "HOLD" button to freeze the current reading on the display. Press again to release.
6. MAX/MIN Function: Press "MAX/MIN" to record the maximum or minimum values during a measurement session.
7. Backlight: Press the backlight button (light bulb icon) to turn the display backlight on or off.

6.2 KAIWEETS Paint Thickness Gauge KOTCO2 Operation

1. Power On/Off: Press the power button to turn the device on. It will automatically power off after 60 seconds of inactivity.
2. Measurement Unit: Press the "µm/mil" button to switch between micrometers (µm) and mils.
3. Making Measurements:
   • Place the probe firmly and perpendicularly onto the surface to be measured.
   • The device will automatically detect the substrate type (Fe for ferrous, NFe for non-ferrous) and display the coating thickness.
   • For continuous measurement, hold the probe on the surface and move it slowly.
4. Data Storage: Press the "REC" button to save the current measurement. The device can store up to 30 sets of data.
5. Setting Alarm Limits: Press the "SET" button to enter the alarm limit setting mode. Use the up/down arrows to adjust the upper and lower limits. An audible alarm will sound if measurements fall outside these limits.
6. Screen Rotation: The display automatically rotates for optimal viewing angle.
