set2: 1 x Sensor Module + 1 x 12V ACID Lead Battery Capacity Indicator Charge Level LED Tester Blue Voltmeter Working current: 5-15mA(The lower the battery voltage and current smaller) Eight electricity Resolution: 10% 25% 40% 50% 60% 75% 90% 100%. Voltmeter accuracy: 1%. Working temperature: -10 ~ +65 Celsius. Module: XH-W1219. Function: Temperature Controller. Power Supply: DC12V. Operating Humidity: 10 ~ 80%. Dimensions: 48 x 29 x 21 mm Color: black & green. Light color: blue. Material: plastic NOTE: It will only display voltage if not measure lead-acid battery!! Please pay attention for your first use. You need wait 6s after your setting data, the module will save the date you have set after 6s. Short press button SET: If you start the time setting mode , Nixie tube will blink. You could adjust the time T1 and T2 by button+ and button-. Please wait 5s after your setting date, the module will save the date you have set after 5s. Long press button SET: if you start the parameter setting mode. There are two group parameter for your choice : P0 and P1. You could switch P0 or P1 by short press SET. Under the parameter P0 and P1,you could set the timing mode by the button+ and button-. P0--0: timing mode is 0--999 seconds; P0--1: timing mode is 0--999 minutes; P0--2: timing when the pattern is 0--999; P1--0: T1 time delay relay (T1 timer); P1--1: T1 delay time relay releases (T1 timer) P1--2: time delay relay after T1 (T1 timer), then the delay time T2 successor electrical release (T2 timing) ends. P1--3: T1 delay time relay releases (T1 timer), then the delay time T2 successor Electric energized (T2 timing) ends. P1--4: time delay relay after T1 (T1 timer), then the delay time T2 successor electrical release (T2 timer), repeat the cycle. P1--5: T1 delay time relay releases (T1 timer), then the delay time T2 successor Electric energized (T2 timer), repeat the cycle.
