HCD194E-2S4 HCD194E-2S7 HCD194E-2S9

HCD194E-2S4: HCD194E-2S4:measure 3-phase voltage,3-phase current, active power,reactive power,frequency,power factor, active electric energy (absorb)and reactive electric energy (inductive).these data can be display by 3-row-4-digit LED and indicators by changing mode, i.e.b by press "→ " and "←" keys, the respective indicator wil light up when select the electric parameter. the active and reactive electric energy displayed by 8-digit LED, the first two rows display the electric parameter, the third row displays the unit, e.g. "0245, 23.67, Wh" means the active electric energy is 24523.67 Wn (i.e.24.5kWh) when the unit indicator does not light up. when display the frequency, the first row displays the unit (Hz), the second row displays the value. the display can switchover by presetting the "DISP" value, then "DISP"=0 the meter will automatically display circularly the voltage, current, power, electric energy and frequency. Note:For 3-phase-4wire system, the meter will display the phase voltage normally, and press"←" key can switch the display between phase voltage and line voltage. for 3-phase-3wire system, the meter will display the line voltage HCD194E-2S7: HCD194E-2S7: measure 4 quadrants electric energy:active electric energy (absorb and release), reactive electric energy (inductive and capacitive),2-row-6-digit LED to display active electric energy (inductive ) respectively.when press down the switch key , the meter will display active electric energy (capacitive ) for a period then turn back to display reactive electric energy (capacitive) or active electric energy (release) HCD194E-2S9: HCD194E-2S9: measure 3 current and 1 active electric energy, 3-row-4-digit LED to display current and 1-row-6-digit LED to display electric energy. the meter must connect the input voltage before measurement ; the display should be zero when the input voltage has not connected and electric energy canot accumulate.
