Chapter 6 Relay contact protection
Electrical spark at the relay contact may affect the life of the relay, especially in an
inductive and capacitive load. In order to inhibit the spark and arc, user should use
an RC circuit to extend the life of the relay.
AC protection, use for inductive load

Chapter 9 HOLD Type
HOLD Type is a safe mode. It is for Calibration, Setting, Record and Clean. In this
mode all the relays are open( inactive), current output follows the setting by
user(last current or fixed current).
The instrument will enter HOLD Type when user presses into Calibration, Setting,
Record or the instrument works in clean mode.
It will in HOLD Type around 10 seconds when it goes back to measurement mode
form the above mentioned 4 modes then left HOLD Type.
The instrument will go into the HOLD Type when turn on the power. Current output
in HOLD Type:
User has two choices: fixed current output or last current output.
Fixed current:
User can set the output current from 4.00 to 20.00mA when instrument goes
into HOLD Type.
Last current:
User can set the output current keep at the last current when instrument
goes into HOLD Type.
Relays in HOLD Type: All relays are opened.(inactive)

10.2 Current 1 settings
1. Set the corresponding 4.00mA to EC/ Resistivity/Salinity/TDS.
2. Set the corresponding 20.00mA to EC/ Resistivity/Salinity/TDS, the
difference between 4.00mA and 20.00 mA at least for EC is
1.00/10.0/100(uS/mS), for Resistivity is 1.00MΩ,for Salinity is 1.00g/kg,for
TDS is 100 ppm.
3. Set the offset current ,the range is± 1.00mA.
4. The filter time range is 0-120 seconds, the low pass filter of software will
active when the current from one point to another point if user sets the filter
time.
5. Set the current 1 output mode(fixed / last) when instrument enter into HOLD
Type.
10.3 Current 2 settings
1. Set the corresponding 4.00mA to temperature.
2. Set the corresponding 20.00mA to temperature, the difference at least
between 4.00mA and 20.00mA is 10.0℃.

3. Set the offset current of temperature, the range is±1.00mA.
4. The filter time range is 0-120s, the low pass filter of software will active
when the current from one point to another point if user sets the filter time.
5. Set the current 2 output mode(fixed / last) when instrument enter into HOLD
Type.
10.4 Relay 1 settings
1. Press UP/DOWN key to ON/OFF (enable/ disable) relay1.
2. Close set point: active point for EC/ Resistivity/Salinity/TDS.
3. Open set point: inactive point for EC/ Resistivity/Salinity/TDS.
4. Delay time: the range is 0-120s. Relay needs to delay first then active if the
measuring data is reach to close set point.
5. For example: If user wants turn on the pump at EC 1000uS and turn off it at
EC 400uS, then the close S.P. needs to set to 1000uS, Open S.P. sets to
400uS.
10.5 Relay 2 settings
1. Press UP/DOWN key to ON/OFF (enable/ disable) relay2.
