●CONNECTIONS
1.Isolating the DC power supply when the non-isolation voltmeter and the
ampere m eter use together , prohibited to use a same DC power source or
two non-isolation DC power supply, otherwise possible to damage the meter.
2. Groups non-isolation voltmeters can use a same DC power supply,
eliminating the input signal and power source's potential difference as far
as possible to avoid display unstable, groups non-isolation ampere meters
can not use a same DC power supply.
3.Before turning on the meter’s power source, please first check the power
source’s polarity and the voltage to avoid damage to the meter.
4.Input signals cable should not too long, better to use twisted-pair shielded
cable; to a void interfere head stream, installing high frequency filtration
electric capacity .

* The mete r’s actual length surpasses the outer covering
l ength, different model s has differen t length.
1. NPN and PNP signal input channel.
2. The length meter and the line speed meter can set prescale value and
decimal point position.
3. Counting speed can choose 30Hz/2000Hz .
4. Frequency&tacho meter max. input rate 10KHz (high type 100KHz).
5. Timer can choose various time range and time method .
6. EEPROM Automatic data storage when power off (option item) .
7. Power voltage DC 5V(Options:DC7~12V/DC7~24V)
FUN1 ON(Short circuit insert): m easure the time form power on or
control signal on.
FUN1 OFF(no-Short circuit insert): It doesn’t displays the time when power
on. m easure the time of control signal on, wi thout control signal keeps the time
value, and the next control signal on. the time reset and measure again.
·Before turning on the meter’s power source, please first inspect the power
source’s polarity and the voltage to avoid damage to the meter.
·Shield line much be used when the measuring input line is getting longer
or there lots of noises
·pleas e use separated line form high voltage line or power line in order
to avoid inductive noises.
·Prevent from violent vibration,shock and cover of heavy dust.
