To review the other basic parameters, just press key then each parameter will be display in turn. While in basic mode, press for over 2 seconds to enter extend measurement mode. For 8912, also press key to switch between volume and capacity.
MAX, MIN & AVG. From the meter is powered on, air temp., dew-point, WBT, humidity & velocity will be temporarily saved in meter, so, to press could view the average value minimum value and maximun value in turns. Press again to back to normal mode. The data will be re-counted once the meter is powered off and turn on again. When in Max./Min./Avg. mode, pressing key to display the parameters you need.

There are three choice to enter the size: - Length & Width: This is the default choice. Press key to select the setting digit first, then press key to select the appropriate value ( 0~9). When select the value, the value will show from 0 to 9 in cycle.
Press key to select the setting digit first, then press key to select the appropriate value ( 0~9) . After selection, short press again to finish the size setting and enter next step.

AIR VOLUME: MEASUREMENT After short pressing to finish and leave size setting, there are 20 second waiting time for you to put the vane to the grill.
After starting measuring the volume, the meter will automatically count the volume for 60 seconds to give a average value. (Fig. J) During this 60 second time, the vane should move along the whole outlet to cover each area so the measured data could be more accuracy. The count down number displayed on the top- left corner as a reminder and meter also beeps when 60 sec is up. After time is up, 60 seconds average volume will display on the LCD as Fig K.

When select the value, the value will show from 0 to 9 in cycle. After entering length, short press to enter width setting. Repeat the procedure of length setting, then short press again to finish the size setting and enter next step. (FIg.

FAN REPLACEMENT If users have more than one set anemometers or users change a new fan for his old meter, user should input the RH% calibration data which enclosed with each fan.
Important Note: While setting the slope, only input 5 digits after decimal point, so user need to round off the 6th digit. User should also input two digits before decimal. Example: a. If the S value is 8.239678, user should input 08 23968 b. If the S value is 11.23968, user should input 11 23968 c. If the S value is 0.2396838, user should input 00 23968 (Fig. S) (Fig. S) Intercept (value Z) 1. While press key save the S setting, the meter will enter intercept input automatically.
User should also input four digits before decimal. All the Z is a negative value but LCD will not appear the negative icon. Example: a. If the Z value is -928.8683, user should input 09 28868 b. If the Z value is -1928.868, user should input 19 28868 c. If the Z value is -89.68482, user should input 00 89685 (Fig. T) (Fig. T) RETURN AUTHORIZATION Authorization must be obtained from the supplier before returning items for any reason.
