Pocket Acidity Meter (Sake)
This unit measures and determines the acidity through electrical conductivity.
The instrument measures the total acidity in end-product Sake.
To measure the acidity of shikomi-process mash, follow the below steps.
１．Use the offset function. Enter 3.29 for coefficient (a) and +0.61 for addition / subtraction (b).
２．Using a digital scale, prepare a 1:60 dilution of the shikomi-process mash.
３．Measure acidity of the 1:60 dilution of the shikomi-process mash.
The Automatic Temperature Compensation (ATC) feature is based on temperature detected by the thermo sensor located
near the sensor area.
ATC may not work correctly when the temperature of the sensor area is not the same as the actual temperature of the
sample. When measuring a hot or cold sample, let it sit on the sensor for approximately 20 seconds and measure, or take
multiple readings until measurements become stable.

mRemove the tape from the battery compartment.
Lo ：The battery power is low. Replace with new alkaline AAA batteries.
O-LD ：The item you are trying to weigh exceeds the permissable weight limit of the scale. Quickly remove it from the scale.
・Do not expose the scale to extreme heat or cold. ・Do not expose the scale to any type of moisture.
・Use between 10 to 30℃ only. ・Use in a dry, clean environment.
・Any contact with or exposure to dust, debris, humidity, strong vibrations, extreme atmospheric conditions or other
electronics may affect the accuracy of the scale and result in unreliable readings.
m
・For precise measurements, place the item you wish to weigh onto the scale gently.
・Place the scale atop a flat, stable surface.
・The digital scale is remarkably durable. However, it is a precision instrument and should be used and treated with the utmost
care.
・Use of the scale for purposes other than its intended use will result in damage to its internal components.
・Do not shake or drop the scale.

Inserting Batteries
The instrument is warranted for one year from the date of purchase. This warranty is void if the instrument shows evidence
of the following. Send the included batteries as well if they are still in use.
・Having been disassembled by unauthorized personnel ・Damages to the sensor section and/or sample stage
・Water damage or having been dropped ・Leakage from batteries other than those included with the unit
・Having been misused and/or operated outside the environmental specifications
Repair services are available for a fee after the warranty expires.

（0～53％）
Store the instrument in a dry
place away from direct sunlight.
Exposure to humidity may cause
condensation inside, and exposure
to direct sunlight may cause the
plastic to warp.
・Cleaning Clean and dry the sensor area thoroughly after
use, leaving no sample residues or water.
〈For oily samples:〉
Remove oily residues with mild soap, and then, rinse with water.
・Storage Store the instrument away from direct sunlight at
a stable temperature with as little fluctuation as possible.
