For Conductivity SI unit (mS/m):
TDS(mg/L) = L(mS/m) × K × 10
For Conductivity older unit ( S/cm): TDS(mg/L) = L( S/cm) × K
K: TDS conversion factor, L: Conductivity
The CPU is monitored by a watchdog timer, and if an abnormal status occurs,
the instrument is switched to warm-up status.

Transmission
Converting pH or temperature to analog signal every input sampling period, outputs theoutput 1value in current. (Factory default: Conductivity)
If Transmission output 1 high limit and low limit are set to the same value, Transmission(TA option)
output 1 will be fixed at 4 mA DC.

Current: 4 to 20 mA DC (Load resistance: Max 550 )Output accuracy: Within 0.3% of Transmission output 1 span
1-point Contact output: See ‘Contact output (EVT option)’.
Transmission
Converting pH or temperature to analog signal every input sampling period, outputs theoutput 2value in current.
(Factory default: Transmission output 1: Conductivity, Transmission output 2: Temperature)(TA2 option)
If Transmission output 2 high limit and low limit are set to the same value, Transmission
output 2 will be fixed at 4 mA DC.
