Control Precision (Dynamic Mode)
PM200-BG2.5K...................................0.005 % Range Span
All other Ranges .................................0.001 % Range Span
Control Turndown ...............................10:1 (Typical)
Control turndown is defined as the relationship between the provided supply pressure and the appropriate supply
pressure for the range. For example, a unit with a 7 MPa (1000 psi) and 700 kPa range (100 psi) with a supply pressure
of 7.7 MPa (1100 psi) will provide control precision of 0.001 % range because 7 MPa is 10 times greater than 700 kPa. A
system with ranges of 20 MPa (3000 psi) and 700 kPa (100 psi) with supply pressure of 22 MPa (3300 psi) will have
0.001 % range control precision on the 20 MPa range but only 0.003 % control precision on the 700 kPa range. Control
precision of 0.001 % on the low range can be achieved by reducing the supply pressure.
Low Control Point ...............................1 kPa (0.15 psi) absolute
Time to Setpoint (Typical)
PM200-BG2.5K...................................40 seconds
PM200, all other ranges .....................20 seconds
PM600 ................................................35-55 seconds
Typical set time is the time required to be within 0.005 % of setpoint for 10 % steps into volumes of 0 to 50 cm3and
pressures above 50 kPa (7.25 psi) absolute. Lower absolute pressures will require longer set times depending upon
quality of the vacuum pump, diameter and material of tubing used, and test volume.
Maximum Overshoot...........................0.01 % Range Span
Pressure Measurement Specifications
The product specifications describe the Absolute Instrumental Uncertainty of the Product. The product specifications
include linearity, hysteresis, repeatability, resolution, reference standard measurement uncertainty, 1 year stability, and

Notes
•Gauge mode modules (PM200-GXXX or PM200-BGXXX) with ranges of 100 kPa (15 psi) or greater will support absolute
mode measurement when used with a Barometric Reference Module.
•For temperatures from 15 °C to 18 °C and 28 °C to 35 °C, add 0.003 % FS/°C. Uncertainty for gauge mode modules
assumes routine zeroing. Uncertainty for absolute mode modules includes 1-year zero stability. This specification can be
reduced to 0.05 % FS if the PM200 module is zeroed on a continuing basis to remove the 1-year zero stability component.
Instrumental Measurement Uncertainty for gauge mode modules used in absolute mode by addition of a barometric
reference module is calculated as the uncertainty of the gauge mode module plus the uncertainty of the barometric reference
module.
•Instrumental Measurement Uncertainty for gauge mode modules used in absolute mode by addition of a barometric
reference module is calculated as the uncertainty of the gauge mode module plus the uncertainty of the barometric reference
module.
•For temperatures from 15 °C to 18 °C and 28 °C to 35 °C, add 0.003 % FS/C.

Notes
•Gauge mode uncertainty is the greater of the relative uncertainty and the threshold uncertainty. For absolute ranges used in gauge
mode there is an additional uncertainty of ±7 Pa for dynamic barometric compensation. When combined with other uncertainties this
changes the threshold uncertainty for the PM600-A100K to 0.008 % Span and for the PM600-A200K to 0.004 % Span.
•For absolute mode the % span for Threshold Uncertainty the span is calculated from zero to the full scale of that range.

To prevent shock hazard, connect the factory-supplied three-
conductor mains power cord to a properly-grounded power
outlet. Do not use a two-conductor adapter or extension cord,
as it will break the protective ground connection.
Mains Voltage
To power the Product, mains voltage ranging from 100 V ac to 240 V ac with
frequencies from 47 Hz to 63 Hz is required.
The Product comes with the appropriate line power plug for the country of
purchase. If a different type is necessary, refer to Table 3 and Figure 1. They list
and show the mains line power plug types available from Fluke Calibration.

Access the Module Bay
Before use, install the Pressure Control Module (PCM) and Pressure
Measurement Module(s) (PMM). After the Product is properly placed (in a
standard 19 inch rack or on a bench top) install the modules in the Module Bay.
Note
The Product rear-panel power switch can be on or off during PMM
exchange or installation.
Before removing the PCM, vent the supply pressure.
To access the Module Bay, see Figure 2:
1. Pull out the handle () located directly below the numeric keypad. This
unlocks the front panel.
2. Pull the handle to slide out front panel and access the Module Bay ().
Note
For safety, the Product automatically vents to atmosphere when the
front panel is unlatched and opened. When the front panel is open,
the system stays in the Vent mode until closed.
For service activity, see the Service Manual for detailed service
processes.
For standard operations, the system pneumatic valves are a
normally closed type. Depending on the chassis power/pressure
down process, differing levels of trapped pressure are possible.
During standard venting processes the maximum trapped pressure
is minimal and may produce a small, safe pressure release when
removing the PCM.
If power is lost to the product, while at high pressure, remove
pressure supply to allow system to mostly depressurize. If possible,
power on system to perform a vent.
Before you open the front panel, remove sensitive, low pressure
devices from the test port. Use the optional Isolation Valve to
improve protection for sensitive pressure devices.

PMM Installation
The PMMs are delivered in a separate box. Install the PMMs with the Product
turned on or off. The PMMs can be installed in any order without the need to plug
any of the unused slots. When the front panel is opened, information such as the
pressure range of each module is shown after it is connected. The Product
detects the PMM information when installed and shows the information in the
Modules menu (see Modules).
To install the PMMs:
Caution
To prevent damage to the sensors inside the modules, do not
drop the modules.
1. Remove the PMM from its shipping box.
2. Remove the protective plastic cover from the PMM test and reference port.
3. Confirm that the test port and reference port O-rings are properly installed on
the module and are not torn or damaged. Additional O-rings are located in the
box in case they become lost or damaged.
4. Open the Module Bay as described in the Access the PMMs and PCMs
section.
5. The PMM has a slot on the bottom of it that fits into the track that lies on the
bottom of the inner Product case, see Figure 2 (). Line the track up with the
slot and slide the PMM into the bottom case until it stops. See Figure 3.
6. Turn the knob on the PMM clockwise until it clicks one time to tighten it.
Note
The PMM knob is a torque-limiting knob that slips once the proper
amount of torque is applied. This prevents accidental over-tightening
that can damage the manifold.
7. After tightening the PMM to the manifold, the module should automatically
appear on the display. Check the main display to see if the PMM is properly
installed.
Note
When the Module Bay is opened, the front-panel display shows the
slots and visually displays the PMMs installed. This provides a
method to quickly ensure the newly installed PMM is connected and
communicating.
8. Repeat this procedure for any other PMMs and BRMs.
9. Close and latch the front panel.
