INPUT SPECIFICATIONS
■ DC Current: 4 – 20 mA DC
Measurable range: 3.75 – 23 mA DC
Maximum input current
Non-approved: 100 mA
Explosion-proof: 23 mA
Intrinsically safe: Refer to ‘Safety Parameters.’
Voltage drop: Approx. 3.7 V with 4 mA
Approx. 4.0 V with 20 mA
The minimum required supply voltage to the 2-wire
transmitter added with the indicator’s voltage drop at the
maximum input current must be within the output voltage
range of the 2-wire transmitter’s excitation supply.
INSTALLATION
Operating temperature: -40 to +85°C (-40 to +185°F)
(See Safety Parameters for use in a hazardous
location.)
Weight: Approx. 1.3 kg (2.9 lb), aluminium
Approx. 4.0 kg (8.8 lb), stainless steel
Approx. 2.0 kg (4.4 lb), TIIS flameproof
PERFORMANCE
Accuracy: ±0.01 mA
Temp. coefficient: ±0.015 %/°C (±0.008 %/°F) at 4 – 20 mA
input
Dielectric strength: 1500 V AC @ 1 minute
(input to outdoor enclosure)
HOW TO CALCULATE ACCURACY AGAINST SCALE
Example 1: 4 – 20 mA input, Scale 0 – 100
Accuracy = 0.01 mA ÷ (20 – 4)mA × 100 = 0.063 %
Display Error = (100 – 0) × 0.063 % = ±0.063 digits
Example 2: 10 – 20 mA input, Scale 100 – 1000
Accuracy = 0.01 mA ÷ (20 – 10)mA × 100 = 0.1 %
Display Error = (1000 – 100) × 0.1 % = ±0.9 digits

The ‘0’ is displayed when the number of decimal places is
set to 2, though the number of effective digits in this case is
reduced by 1 digit compared from the 3 decimal places.
Select appropriately for the application. Refer to
‘Programming Procedure’ for how to choose decimal point
positions.
DISPLAY DESCRIPTIONS
■ DISPLAY DIGITS
The decimal point position may shift according to the
required number of digits for the integer section, even when
more than one decimal places have been specified.
However, when the number of decimal places is set to 3,
the ‘0’ in the integer section is not shown in order to secure
the number of effective digits, as explained in the table
below.
