5. Setup

5.1 Battery Installation

Both the HT118E and HT206D require batteries for operation. Locate the battery compartment on the back of each device. Use a screwdriver to open the compartment, insert the batteries according to the polarity indicators, and then secure the cover.

5.2 Connecting Test Leads

For most measurements (voltage, resistance, capacitance, etc.), connect the black test lead to the "COM" (common) input jack and the red test lead to the appropriate input jack based on the desired measurement (e.g., VΩmA for HT118E, INPUT for HT206D).

6. Operating Instructions

6.1 General Operation

• Turn the rotary dial to the desired measurement function.
• Connect the test leads to the circuit or component being measured.
• Read the measurement value on the display.
• The devices feature auto-ranging, automatically selecting the correct range for the measurement.
• Both meters have a backlight for improved visibility in dim environments. Press the backlight button (often combined with the flashlight button) to activate it.
