Introduction
The industrial pH meter HP-100 consists of the pH sensor, the sensor holder, the transmitter,
and the power unit that supplies the power to these components through two lines, receives
signal and provides the output to the extemal receiving instrument.
This manual provides explanation for the two-wired transmitter. For other units, refer to
individual instruction manuals.
This transmitter is a field insulating-type converter. By connecting the lead wire of the
electrode of fixture and connecting power supply of approx. 22.5 V to 30 V DC, this converter
transmits the pH measured value as a signal of 4 mA to 20 mA DC, overlapping the supply
power line (2 wires).
The measured value is displayed on the LC digital meter.

JWiring of Two-wired Transmission
QPower switch
This instrument has no power switch. Install a power switch.
QConnecting the power supply
The power supply is 2-wire transmission power source that rated voltage is 22.5 V to 30 V DC.
As illustrated below, connect the power cable and grounding cable.
WARNING
If there is a possible of lighting damage, install lighting arresters both at the instrument and receive
device.
ELECTRIC SHOCK
Make sure that no electric power is supplied to the instrument before staring this work.
CAUTION
• Operating the instrument using a voltage out of the rated range may cause it to malfunction. Be
sure to check the voltage of the power supply. Also make sure that the fluctuation of the power
supply voltage is within the range of 22.5 V to 30 V.
• Use a balanced type shield cable.
• If there is a possible of lighting damage, install an arrester in two place between the HP-100 and
the distributor.

Fixing the Rear Cover
There are small protrusions in the rear cover and the main unit case. To tighten the cover,
align these protrusions and screw straight. If they are obliquely inserted, the cover cannot be
colsed completely.
Mounting the Hood
To mount the hood (FD-10) provided as an option, use screws on the opposite side where
metal fitting for 50 A pipe is attached.
Air Purge
The two tapped holes of PF 1/8 screw are the side of STD/SLOPE control on the bottom of the
transmitter. The tapped holes are used to be the inlet and outlet ports of air purge after boring
a hole to the inside of the transmitter and connecting the air pipe joints. The air purge is
required in the environment of corrosive gas or huge humidity.

Calibration and Measurement
pH Calibration
JSTD control and SLOPE control
STD control and SLOPE control are connected to the volume through the shaft and pin, as
following diagram.
Push the control with turning to connect the pin and the volume.
Soak the electrode in the standard solution.
Set the value of the LCD display to the value of the standard solution with STD/SLOPE
controls.
zSTD control
Adjust the value of the LCD display to the value of the pH7 standard solutioin affected by
the temperature. (example: pH6.86 25°C).
zSLOPE control
Adjust the value of the LCD display to the value of the pH7 standard solutioin affected the
temperature. (example: pH4.01 25°C of pH9.18 25°C).
Calibrate other standard solution according to the explanation for that standard solution.
