Because the ⑱ Indicate temperature range set at HI or LO at CH1 & CH2 signal of sensor unit is blocked and can't transmit to main unit ⑲...
Ⅲ. Power on process Demonstration of measurement (A). Battery installation Always install main unit first and then sensor unit. Follow water temperature instruction of A & B as below to enable transmitting and of aquarium WIRELESS THERMOMETER receiving in good work. TRANSMITTER 1.
2. Once batteries are installed the full segment will display on LCD B. Battery installation of sensor unit for 2 seconds. Follow the steps from dwg#1 to dwg# 7 to complete the installation. CH1 temperature (1) Loose 2 screws on battery door with Philips screw driver. (2) Do not attempt to loose 4 crews marked on dwg#2.
Attention: Do not attempt to loose the screws marked. (C). Set up time (clock) After power on must set up clock immediately enable to work dwg#1 dwg#2 with the relevant functions 1. Hold MODE key for 3 seconds to access time set function as dwg#2.
Ⅳ. Application of thermometer 《ATTENTION》 a. Time set can only operate in simple measuring mode as (A) Key function: dwg#1. In MAX/MIN, LGR or alarm mode can't operate time set as dwg.#6. MODE key shift 4 modes display b. In case, accidentally push MAX/MIN key MAX, MIN symbol 1.
(1) CH1 & CH2 temperature display ( C) ° (B) Measurement of temperature a. Change display to the simple measuring mode as dwg#1 below. Hold MODE key simple measuring b. Upper layer display of CH1 is for the temperature >3 seconds mode display measured by the thermocouple at A socket.
(C) Set up alarm function ( e. Set HI or LO temperature: (1) Set up temperature alarm of CH1 and CH2: in condition ● Only one option to set alarm range at HI or LO of the temperature reaches and higher beyong ( ≧HI ) temperature.
(D) Read temperature record (LGR CALL) f. Activate alarm function ( display): (1) 12 hours auto data logging for CH1 and CH2 ● Push MODE key to switch dwg#1 to dwg#2 temperature corresponds with real time record. Recording is every 30 minutes with 24 sets maximum. Once capacity is full will start over the recording cycle CH1 temperature from the beginning and the old record will be replaced.
(F) MAX / MIN temperature (E) Search temperature of sensor unit (1) Push SEARCH key for manual search of signal from (1) Maximum / Minimum temperature recording function sensor unit. Every search is lasting 5 minutes. If 5 (set clock before entering MAX/MIN mode). Set minutest search is failed the radius symbol ( MAX/MIN mode starting from dwg#1.
(H) Trouble shooting of main unit (1) Either in MAX/MIN mode, alarm mode or reading temperature record (LGR) mode, can't operate push MAX/MIN key push MAX/MIN key temperate range alarm setting or clock set. All functions only enable at the simple measuring mode. (as below drawing status 1 ~ 3) dwg#5 dwg#6...
