5.Usage

4.1 Precautions

a. Before using this instrument, one should first read the instrument manual and become familiar with the operating methods;

b. This instrument usually works normally after a few minutes of startup. For precision testing, the preheating time is 15 minutes.

4.2 Button Introduction

There are a total of 11 buttons on the front panel of YS-2499A, including 4 function keys, menu key, zero adjustment key, calibration key, and four directional keys. There is a power button at the power input interface on the back panel that controls the power on/off.

a. Function keys

YS-2499A has 4 function keys used to select submenus under each menu page.

b. Menu key

This key is mainly used for switching between menu pages.

c. Zero adjustment key

This key is mainly used for zeroing instruments

d. Correction key

This key is used for instrument calibration

e. Direction keys

YS-2499A has four directions: up, down, left, and right. The up and down keys are mainly used for numerical addition and subtraction, while the left and right keys are mainly used for cursor movement under submenus.

4.3 Menu Introduction

YS-2499A has set up 5 menus, namely Menu1 Menu2、Menu3、Menu4、Meau5， They switch through menu keys, pressing the corresponding function key on the right side of each submenu, and then using the up, down, left, and right arrow keys to operate the submenu or set the corresponding parameters.
