Operating Precautions

Handling the Instrument

The maximum rated voltage between input terminals and ground is 30 VAC/ 60 VDC. Attempting to measure voltages exceeding 30 VAC/ 60 VDC with respect to ground could damage the instrument and result in personal injury.

• This instrument is designed for safe operation only at low voltage. Ensure that no more than 60 V is present between any terminal and ground, and that the potential difference between any two terminals does not exceed 60 V. The instrument cannot be guaranteed in an overrange situation, such as due to an inadvertent electric shock or faulty insulation, and we cannot accept responsibility for any consequences that might occur from misuse.

• The output terminals and the voltage and current input terminals (terminals for the standard resistor) are all isolated. Before connecting the terminals, ensure that the target device will not provide excessive output to, or require excessive input from, the terminals. The instrument cannot be guaranteed in an overrange situation, such as due to an inadvertent electric shock or faulty insulation, and we cannot accept responsibility for any consequences that might occur from misuse.

• Ensure that the input does not exceed the maximum input voltage or current to avoid instrument damage, short-circuiting and electric shock resulting from heat building.

• Do not allow the instrument to get wet, and do not take measurements with wet hands. This may cause an electric shock.

• The case is not hermetically sealed for protection against explosion, so do not use in a flammable atmosphere.

Page 12

Operating Precautions

• When the power is turned off, do not apply voltage to the voltage input terminals. Doing so may damage the instrument.

• To avoid damage to the instrument, protect it from physical shock when transporting and handling. Be especially careful to avoid physical shock from dropping.

• If this instrument has been vibrated or impacted, restart it before use.

• Before sourcing or measurement, make sure of the function position. If current or voltage in excess of sourcing or measurement range is input, the instrument may be damaged.

• Note that the instrument may be damaged if the applied voltage or current exceeds the measurement range.

• If output is impossible when is displayed which indicates outputting, set to with OUTPUT ON/OFF key and set output to ON again.

• To avoid corrosion and damage to this instrument from battery leakage, remove the batteries from the instrument if it is to be stored for a long time.

To avoid problems with battery operation, remove the batteries from the instrument if it is to be stored for a long time.

Page 13

Operating Precautions

Handling the Cords

• Before using the instrument, make sure that the insulation on the test lead and input cord is undamaged and that no bare conductors are improperly exposed. Using the instrument in such conditions could cause an electric shock, so contact your dealer or Hioki representative for repair.

• Use the 9168 Input Cord with DC 28 V or less. If this level is exceeded, electric shock may occur.

• Always turn both devices OFF when connecting and disconnecting an interface connector. Otherwise, an electric shock accident may occur.

• To avoid breaking the test lead and input cord, do not bend or pull them.

• For safety reasons, when taking measurements, only use the L9170-10 Test lead provided with the instrument.

Page 14

Operating Precautions

Handling the AC Adapter and the Nickel Hydride Batteries

• Turn the instrument off before connecting the AC adapter to the instrument and to AC power.

• Use only the supplied Model 9445-02 AC Adapter or Model 9445-03 AC Adapter. AC adapter input voltage range is 100 to 240 VAC (with ±10% stability) at 50/60 Hz. To avoid electrical hazards and damage to the instrument, do not apply voltage outside of this range.

• To avoid damaging the power cord, grasp the plug, not the cord, when unplugging it from the power outlet.

The nickel hydride battery is subject to self-discharge. Be sure to charge the nickel hydride batteries before initial use. If the battery capacity remains very low after correct recharging, the useful battery life is at an end.

2.2 Connecting the Input Cord and the Test Lead

• To avoid electrical accidents, confirm that all connections are secure. The increased resistance of loose connections can lead to overheating and fire.

• Be sure to connect the voltage input and current input terminals correctly. An incorrect connection could damage or short circuit this instrument.

Page 33

2.2 Connecting the Input Cord and the Test Lead

• When switching the power on and off, remove the target device from all terminals. Furthermore, always set the output to OFF when connecting or disconnecting the output terminal and target device. In either of these cases, failure to heed this caution may result in damage to the instrument or to the target device.

• Do not input current more than 25 mA DC to the terminal for the standard resistor. Doing so may damage the resistor of the instrument.

• Output terminal and current input terminal have circuit protection fuses. If the fuse is blown, output or current measurement is impossible. Exchange the fuses before operation.

See: "8.2 Replacing the Circuit Protection Fuse" (p.94)

• When output is off, the output terminals are shorted

with a resistance of about 50 kΩ.

• Input resistance of the voltage input terminal is

approx. 1 MΩ and that of the current input terminal is approx. 30 Ω.

Page 34

2.3 Turning the Power On and Off

Before turning the instrument on, make sure the supply voltage matches that indicated on the AC adapter. Connection to an improper supply voltage may damage the instrument or AC adapter and present an electrical hazard.

When switching the power on and off, remove the target device from all terminals. Furthermore, always set the output to OFF when connecting or disconnecting the output terminal and target device. In either of these cases, failure to heed this caution may result in damage to the instrument or to the target device.

• If power switch is set to on ( ) for the instrument, even when sourcing or measurement is not executed current is still consumed. The lifetime of battery therefore shortens. The power switch should be turned off ( ) when unused.

• Because turning the power on or off places a load on the instrument, wait at least 5 seconds before turning the power off or on again.

• If the power doesn’t turn on when turning on the power again, turn the power off and leave for more than 5 seconds.

• The warm-up time of this instrument is 5 minutes. Source values and measurement values can be unstable within 5 minutes after turning the power on.

3.1 Sourcing Example

The SS7012 can source constant voltage, constant current, and standard register. Instead of the thermocouple, a voltage corresponding to a specified temperature can be sourced.

Constant voltage (CV) (p.39)

In [CV:2.5V], constant voltage can be sourced from -2.5 to +2.5 V with the resolution of 100 µV. In [CV:25V], constant voltage can be sourced from -25 to +25 V with the resolution of 1 mV.

Constant current (CC) (p.39)

In [CC:25mA], constant current can be sourced from -25 to +25 mA with the resolution of 1 µA.

Thermocouple (TC) (p.43)

In [TC], voltage can be sourced according to the setting temperature instead of thermocouples. Eight types of thermocouples are supported: K, E, J, T, R, S, B, and N. Thermometers using thermocouples can be calibrated.

Standard register (Rs) (p.50)

100 Ω standard resistor is connected to the terminal for the standard resistor (current input terminal). The resister can be used for the 0°C check of the 100 Ω standard resistance thermometer.

Output monitor function (p.51)

When a constant voltage is sourced, the current flowing in the target device can be monitored. (this function is used when testing the twowire transmitter in a loop test.) When a constant current is sourced, the voltage between the output terminals can be monitored. When a thermoelectromotive force is sourced, the reference junction temperature can be monitored. ("0°C" is displayed in [TC:0°C], the temperature measured with the optional 9184 Temperature Probe is displayed in [TC:RJ])

Memory source function (p.54)

Values to be sourced can be recorded ahead of time. The recorded value can be switched using a single key operation or automatically. (When testing a distributor in the loop test, 4-20 mA can be easily sourced.) For each source function, up to 20 values can be recorded.

3.7 When setting value is flashing

When the OUTPUT key is pressed and output is set to ON, setting value may flash. When setting value is flashing, the value being output may be lower than the setting value. (Overload) Press the OUTPUT key to set the output to OFF. Check the connection of the SS7012 and the target device. If there are unexpected shorts or contact failures, eliminate them. If the setting value is still flashing even after setting output to ON, the performance level of the SS7012 is being exceeded. (See below.)

In the constant voltage source function of this instrument, the possible electrical current that can flow is ±25 mA. (Current must flow to source the specified constant voltage.) If a current exceeding ±25 mA flows, the source voltage may become lower than the setting value. In other words, the set voltage cannot be sourced in this condition. Furthermore, in the constant current source function, the applied voltage is ±25 V. (Voltage must be applied for the specified constant current to flow.) If a voltage exceeding ±25 V is applied, the source current may become lower than the setting value. In other words, the set current cannot be sourced in this condition.

5.1 Loop Test Overview

Loop tests can be performed with the SS7012. The loop tests are for systems that include two-wire transmitters and distributors. (See the diagram below). Two-wire transmitters and distributors can be tested using the SS7012. The two-wire transmitter receives the sensor output and converts it to a 4-20 mA current signal. In addition to supplying the power to the two-wire transmitter, the distributor outputs a signal corresponding to the current signal to a later stage.

5.2 Testing a Distributor (4-20 mA)

The 4-20 mA current flow of the distributor can be tested by using the SS7012 to sink the 4-20 mA current (a two-wire transmitter simulation). For the distributor test, setting values of the source current are minus because the SS7012 sinks current. It is assumed that the memory source function setting of the SS7012 is default. When the setting is not at the default, initialize the memory settings or set -4 mA/ -8 mA/ -12 mA/

-16 mA/ -20 mA.

8.1 Troubleshooting

Maintenance and Service Chapter 8

8.1 Troubleshooting

Do not attempt to modify, disassemble or repair the instrument; as fire, electric shock and injury could result.

• If damage is suspected, check the "Before returning for repair" (p.93) before contacting your dealer or Hioki representative.

• Getting the instrument wet or letting oil or dust enter inside its casing will certainly damage it, and is quite likely to cause an electric shock accident or a dangerous conflagration. If the instrument has gotten seriously wet, oily, or dusty, stop using it and send it for service at an approved Hioki calibration facility.

Transporting

When sending the instrument for repair, remove the batteries and pack carefully to prevent damage in transit. Include cushioning material so the instrument cannot move within the package. Be sure to include details of the problem. Hioki cannot be responsible for damage that occurs during shipment.

Page 88

8.1 Troubleshooting

Replaceable Parts and Operating Lifetimes

Useful life depends on the operating environment and frequency of use. Operation cannot be guaranteed beyond the following periods. For replacement parts, contact your dealer or Hioki representative.

Part Life

Electrolytic Capacitors Approx. 9 years

There is a fuse inside in the power unit of the instrument. If the power does not turn on, the fuse may be blown. If this occurs, a replacement or repair cannot be performed by customers. Please contact your dealer or Hioki representative.

8.2 Replacing the Circuit Protection Fuse

• To avoid electric shock, turn off the power switch and disconnect the test leads or input cords from the target device before replacing the fuse.

• After replacing the batteries, replace the cover before using the instrument.

• Replace the fuse only with one of the specified characteristics and voltage and current ratings. Never use unspecified fuses and never use the instrument after the fuse holder has shorted. This will damage the instrument and cause injury. Fuse type: 250VF50mAH (φ5.2 ×

The fuses are fitted on the PCB where the lower case is removed.

• The SS7012 has three fuses: two of them are for source function, one for measure function. Fuses are common for all the function.

• The fuse for the constant voltage ([CV:2.5V], [CV:25V]) and constant current ([CC:25mA]) source functions is labeled "F201" on the circuit board.

• The fuse for the thermoelectromotive force source functions ([TC:0°C] and [TC:RJ]) is labeled "F202" on the circuit board.

• The fuse for the current measure function ([A:25mA]) is labeled "F401" on the circuit board.
