INSTRUCTION MANUAL
ANALOG CALIBRATOR

◆ Preface

Thank you for purchasing our SHN - CAL made by Shinho System Co., Ltd. This manual
describes specifications and information for you to install and maintain the product. For
any problem or question during use, contact our Sales Department of Head Office or local
dealer.

◆ Overview

SHN-CAL is a 2-wre transmitter simulation tester and source (mA) calibrator.
It is also a multi-functional analog calibrator equipped with functions for measurement of
mA Output, power supply and measurement of 2-wire transmitter, and Measurement of
DC voltage for checking of loop power.
<Features>
▷ Compact and light weight for each carrying.
▷ Proud of high accuracy of ±0.03% using high performance and high accuracy 16bit
A/D converter. (±0.01mA error at 4~20mA)
▷ Long time service with built-in Li-Polymer battery.
(Max. 13 hours on +24Vdc 20mA output)
▷ Fast switching with a slide switch.
▷ Indicating 0~25mA or -25.0~125.0% with 4-digit display.

◆ Operation Method
①
1. Source mA
(4~20mA Output)
2. Read mA
(24V Powered Measure)
3. Read mA
(mA Measure)
4. Read Vdc
(Vdc Measure)
5. 2-Wire Transmitter
(Non Power)

1. Source mA Output Mode

■ This function is used to supply 0.00 ~ 24.00mA Output.
Check operation of your mA receiver with DC 24V output voltage.
1) Draw out one input wire from the instrument to be calibrated.
2) Move the central slide switch to mA or % and the right slide switch to
3) Connect (+) input of the instrument to a red source line of the calibrator and (-)
input to a black source line.
4) Turn the nob to adjust output current.

2. Read mA (+24Vdc Powered Measure) Mode

■ This function is used to measure the output current from the transmitter by
supplying +24Vdc.
1) Draw out output wires from the instrument to be calibrated.
2) Press +24Vdc powered S/W with slide switches at Source mA Output Mode
(+24V LED On)
3) Connect Red wire (+) and Black wire (-) of the calibrator to + and – of
the Output, respectively.
4) Check if the current is put out within a range of 0.00~45.00mA.

3. Read mA (Current Measurement) Mode

■ This function is used to measure 0.00 ~ 45.00mA or -25.0~260.0%.
1) Connect one current loop of convenient part of the signal line.
2) Move the central slide switch to mA or % and the right slide switch to
3) Connect Red wire (+) and Black wire (-) of the calibrator to + and –
of the Output, respectively.
4) Check if the current is put out within a range 0.00~55.00mA.

4. Read Vdc (Voltage Measurement) Mode

■ This function is used to measure 0.00~+70.00Vdc.
1) Move the central slide switch to mA or % and the right slide switch to
2)
Connect Red wire (+) of the calibrator to + and Black wire (-) to –
pole of the voltage to be measured
range of 0~70.00V.
3) When signal voltage of the loop power supply receiver exceeds DC 100V,
the internal fuse is disconnected
.

5. 2-Wire Transmitter Simulation Test

■ This function is used to simulate a test for 0.00 ~ 24.00mA output from 2-Wire
transmitter.
1) Disconnect and loose one or both inputs from the instrument to be
calibrated.
2) Move the central slide switch to mA or % and the right slide switch to
3) Connect Red wire (+) and Black wire (-) of the calibrator to + and –
of the Output, respectively.
4) Turn the nob to adjust output current.
For other problems than described above, please contact our head office.
