INTRODUCTION
The Model 1056 is a bench top, line power instrument designed for the measurement of Conductivity covering six ranges from 0 to 199.9
milli Siemens (mS). The bright red 3 1/2 digit L.E.D. display has a floating decimal and indicates whether displayed measurement is in
micro Siemens (µS) or milli Siemens (mS) [note: mho = Siemens].
The meter features two front panel controls, one for selecting the Range (A-F) and one for the "Calibrate" control
adjustment. The Model 1056 has a function switch on the rear panel for selecting ATC On or Off, both referenced to 25°C. A
self-test mode allows the user to check the calibration reference point. The Power Entry Module (PEM) allows for either 115 VAC or
230 VAC operation. The recorder output is 1 volt per 1000 counts from a 1 K ohm source. A tilt stand / handle and cell holder are
included.
