“t”: Represents the way Settings for counting/counting meters
Power outage memory setting
“A” Buzzer switch setting
“P” Decimal point position setting
"F1" counts speed Settings
"F2" indicates the counting speed setting
"H1" stands for counting times/meter length cycle setting
"H2" denotes counting times/meter length setting
"U" denotes relay release value setting
Represents the automatic reset time setting
"d" means delay conduction time setting
"O" indicates conduction time setting
"C" stands for multiplier Settings
1、Users can modify the parameters, all set values even if the power is lost，Please refer to the technical parameters for setting range；
2、Counting method, counting, technology to a predetermined number of times, there will be a second alarm prompt. The alarm prompt switch can be switched through J8, '0' means on, 'C' means off.
3、Working mode of the relay: the counting times reach the preset times, the relay is engaged, and the relay is released after reset。
4、The meter has the cumulative number view function and reset function, and the shift key "<" is the cumulative number view key, and “∧” is the digits reset key.
5、Long press the shift button for 2 seconds "<", the hand guard shows the accumulative number, and the digital tube flashes display. Release and press the shift button again for 2 seconds, and the accumulative number can be reset. Adding button “∧”back to the technical interface or no key operation, and automatically enter the counting interface after 2 seconds.
6、The power supply USES the polarity protection line, the power connection will not damage the instrument.
7、DC5V and dc7-30v can be switched through J7.
8、The default setting is DC7-30v.(note: when J7 jumper is switched to DC5V, DC7-30v voltage cannot be supplied to the meter)
9、After a power failure, memories can last for 10 years.
Setting operation:
When entering the parameter setting, just press the "SET" key for 3 seconds to enter the parameter setting.
Parameter Settings can be set during both idle and counting. During the setting process, if there is no operation button within 10 seconds, the meter will automatically exit the setting interface and save the setting parameters this time.
When setting parameters in the counting process, the instrument will only execute the previous parameters, and the parameters set this time will be executed after exiting the setting interface.
Counting frequency cycle setting:
long press the "SET" button for 3 seconds, and the nixie tube will display "F1", indicating the setting and setting method of counting frequency cycle; Click the shift "<" or adding button “∧”, and the units digit will blink and show (what digit twinkles, and the corresponding digit can be set);In adding button “∧”, the ones digit would change from 0-9, and after adding the ones digit, the "<" would shift again, and the tens digit would twinkle...
Conduction time setting:
When the counter cycle is SET, press the "SET" key again, and the digital tube displays "F2", indicating the on-time setting. The setting method is the same as the technology frequency cycle setting. The maximum conduction time is 999.8 seconds. When set to "999.9", it means that the circuit is always on. When set to "000.0", it means that this function is turned off.
Automatic reset time setting:
When the on-time setting is completed, press the "SET" button again, and the nifty tube will display the "SET" key and the nifty tube will display the "F3", indicating the automatic reset time setting. The setting method is the same as the counting times cycle setting.
The maximum conduction time is "999.9" seconds. When set to "000.0", this function will be turned off.
Counting speed setting:
When the automatic reset time is SET, press the SET button again, and the digital tube will display "F4", indicating the setting of counting speed, in units of XXX/s and -xxx/s.
When the counting speed is SET, press "SET" again and go back to the counting interface. The whole setting is completed.
The parameter meter will be executed immediately
