8818S only need two button type battery (392A:LR41:AG3:V3GA) is available for five hours of continuous use

Install the battery, first with anti clockwise loosen pencil induction, remove bullets (axial part) gently move the wire (attached to the battery), a new battery after reduction.
note: 1 if the pencil induction portion from the pen body, please do not use the test pencil.
2 pencil part must ensure that fully tightened (clockwise direction) can be safe to use.
3 all models have a large transparent shell, inside the red light visible, high light transmittance, suitable for indoor and outdoor use. Battery device for use
1 AC test: contact (70-250VAC) do not contact (70-10.000VAC)
2 DC test: up to 250VDC

3 polarity: 1.5V-36VDC

4. high impedance: 0-50

note 1) do not go beyond the above description of the voltage test.
2) normal working environment is -10 DEG C to 50 DEG C, and between 50-500HZ.
3) under the following conditions:
visibility will weaken a: negative light dark environment (such as light 'red light' shows no obvious).

, check whether
has power, fast, convenient and time-saving, check the computer display, the light that there is radiation,
prevent children watch too close to the eyes, so as to avoid damage by a simple method to test the
kinds of household electrical appliances - fast check lamp, good and bad, can distinguish the lamp wire plug. On and off - DC transformer and battery polarity difference - check line or barge accurate fault, an easy job to do. Positive and negative - red light red light (1.2-36VDC)

must be self before use

Do not use
pressure test in too humid environment 1.5V-500V
as the value of friction will light (indicating that pencil electrostatic
multipurpose) the latest electronic products
the products such as the use of appropriate measurement function can be developed more
