Press the DC switch on the back of the instrument to check the voltage indicating bar code (bar code is five bars). If only the last bar is slightly bright, the battery needs to be charged.

1. Preparation before use:

Press the DC switch on the back of the instrument to check the voltage indicating bar code (bar code is five bars). If only the last bar is slightly bright, the battery needs to be charged.

2. Charging:

The instrument set charging time for 7 hours, plug in the power plug, press the backplane DC switch, panel voltage indicator bar code bright, and then press the panel charging button, charging indicator light on charging start, at the same time the digital tube panel display charging time 420 minutes, charging time set as a countdown. Digital tube display all zero, charging indicator light off, charging finished. During the charging period, the power will be cut off, no matter how long the time, after the call will continue to charge. If the instrument needs to work during the charging period, press the reset button. Charging process, bar code should be all bright, if not bright charging failure, must be removed after charging.

3. Sampling:

(1) During sampling, expand the "tripod", place the instrument host on it, and tighten the screws on the "tripod". Its height within 0.7~1.7m can be adjusted according to the need, to the operator in front of the "rotor flowmeter" scale is the most appropriate.

(2) Install the two "sampling heads" on the sampling filter membrane, install them on the two "sampling heads" on the back plane, and tighten them.

(3) Flow regulation, first of all to set the flow regulation, time 1 minute. Open the backplane DC switch, the motor starts instantaneously, when the "digital tube" is all zero stop, press the "plus" key, make the "digital tube" is 1, and then press the "sampling" key, the pump starts to work, unscrew the "flow regulating valve", the flow is adjusted to the required flow, you can also use the flow regulating valve for fine tuning, adjust the flow regulating knob on the side of the instrument, to 1 minute later, it will automatically stop.

(4) Set, press the "plus" button and do not release until the required time, release will stop.

(5) Press the "sampling" button of the weighing device, sampling starts, and sampling stops automatically when the sampling time drops to zero. If you need to stop sampling, press the "sampling" button again to stop.
