Faults and Damage
Applying a voltage greater than 28 V to the input of the Calibrator invalidates its Ex Approval and may impair its safe operation in an Ex- hazardous area.
If there is any reason to suspect that the safe operation of the Calibrator has been affected, it must be immediately withdrawn from use, and precautionary measures must be taken to prevent any further use of the Calibrator in an  Exhazardous area.
The safety features and integrity of the unit may be compromised by any of the following:

• External damage to the housing
• Internal damage to the Calibrator
• Exposure to excessive loads
• Incorrect storage of the unit
• Damage sustained in transit
• Correct certification is illegible
• Using the product with the red holster removed
• Functioning errors occur
• Permitted limitations are exceeded
• Functioning errors or obvious measurement inaccuracies occur which prevent further measurement by the Calibrator

Safety Regulations
The use of this 707Ex mA Calibrator meets the requirements of the regulations providing that the user observes and applies the requirements as laid down in the regulations and that improper and incorrect use of the unit is avoided.

• Use must be restricted to the specified application parameters.
• Do not open the Calibrator.
• Do not remove or install the battery within the Ex-hazardous area.
• Do not carry additional batteries within the Ex-hazardous area.
• Use only type-tested batteries. The use of any other battery will invalidate the Ex-certification and present a safety risk.
• Do not use the Calibrator in an Ex-hazardous area unless it is completely and securely fitted in its accompanying red holster.
• After using the Calibrator in a non-intrinsically safe protected circuit, a rest time of 3 minutes minimum duration must occur before the Calibrator is taken into and/or used in an Ex-hazardous area.

Front Panel Controls

Using the mA Sourcing (Output) Modes
The Calibrator outputs current for calibrating and testing 0 to 20 mA and 4 to 20 mA current loops and instruments.
In SOURCE mode, the Calibrator supplies the current.
In SIMULATE mode, the Calibrator simulates a 2-wire transmitter in an externally powered current loop.
Changing the mA Output Span
The Calibrator has two mA output spans:

•  4 mA to 20 mA (0 % to 100 %) [default]
• 0 mA to 20 mA (0 % to 100 %) [optional]

To change the output span, turn the Calibrator off. Press A + D simultaneously. The selected setting is saved until it is changed again.
Sourcing mA
Use SOURCE mode to supply current to a passive circuit.
A path must exist for current to flow between the + and the COM terminals. Otherwise, the display flashes when you set an output value.

Simulating a Transmitter

When simulating the operation of a transmitter, the Calibrator regulates the loop current to a known value selected by you.
A 12 V to 28 V loop supply must be available. Insert the test leads as shown below.

Auto Ramping the mA Output
Auto ramping allows you to continuously apply a varying current from the Calibrator to a passive (sourcing) or active (simulate) loop. Your hands remain free to test the transmitter’s response.
Press B + C simultaneously to enter the Auto Ramp mode and step to a ramp type.
The Calibrator applies or controls a continuously repeating mA signal over a 0-20 mA or a 4-20 mA span in one of three ramp types:
Slow (e) 0 % to 100 % to 0 % smooth ramp over 40 sec.
Fast (g) 0 % to 100 % to 0 % smooth ramp over 15 sec.
Step (f) 0 % to 100 % to 0 % stair-step ramp in 25 % steps, pausing 5 sec at each step.
To exit, press any pushbutton or turn the Calibrator off.

Using the SpanCheck Function

When in source mode the SpanCheck™ function checks the zero and span points of a transmitter in either SOURCE or SIMULATE mode.
To select SpanCheck, press C.
To exit, press any pushbutton or turn the knob.
